APPLICATION FIELD
The Dynasonics® UHC100 ultrasonic heating and cooling energy meter (hereinafter referred to as“the meter”) is designed to
measure the consumption of heating and cooling energy and record data in two separate registers. It is used in individual or
district heating facilities (for example, residential buildings, enterprises, organizations or supply facilities) for the commercial
metering of consumed energy where water is the heat carrier.
This is a compact microprocessor meter for mounting optionally either at the supply or return heat exchange circulation
system with permanently connected temperature sensors.
The meter complies with the requirements of Annex 1, Annex MI004 to the Technical Regulation on Measuring Instruments
and harmonized standards LST EN 1434 – Heat meters (LST EN 1434-1:2016, LST EN 1434-2:2016, LST EN 1434-3:2016, LST EN
1434-4:2016, LST EN 1434-5:2016).
The meter meets the requirements of Environmental Class C according to LST EN1434-1:2016.
Climatic Environmental Conditions: Temperature range: 41…131° F (5…55 °C)
Humidity: Condensing
Location: Closed
Mechanical Environment Class: M1
Electromagnetic Environment Class: E2
MEASUREMENT CANADA
The meter is approved by Measurement Canada in accordance with regulations and specifications established under the
Weights and Measures Act as a thermal energy meter for heating type systems in residential, commercial, industrial and
institutional usage.

OPERATING PRINCIPLE
The flow rate is measured on the basis of the ultrasonic measurement principle. The ultrasonic signal is sent along the flow
sensor upstream and downstream between the ultrasonic sensors, which alternately perform transmitter and receiver
functions. The flow rate is calculated on the basis of the measured propagation time difference (downstream and upstream).
The temperature differential between the supply and return flows is measured by resistive temperature sensors. The
electronic unit calculates the amount of consumed heat energy by integrating over time the difference of the enthalpies of
supply and return heat carrier and provides the data on the display.
Energy calculation formulas:
When the flow sensor is in the supply line: Q = V * ρ * (hT1-hT2)
When the flow sensor is in the return line: Q = V * ρ * (hT1-hT2)
Where:
Q = Heat energy
V = The volume of water passing through the meter, m³
ρ1, ρ2= The water density corresponding to the supply and return heat carrier temperatures Θ1 and Θ2 measured by the
supply and return water temperature sensors T1and T2
hT1, hT2= The calculated specific enthalpy of the heat carrier for the temperatures Θ1 – Θ2
When the cooling energy tariff function is activated, in case of a negative temperature differential, energy will be accumulated
in the additional tariff register Q☼. In this case, energy values are calculated according to the following formulas:
When the flow sensor is in the supply line
when Θ1 > Θ2: Q = V * ρ1* (hT1-hT2), Q☼= 0
when Θ1 < Θ2: Q☼= V * ρ1* (hT2-hT1), Q = 0
When the flow sensor is in the return line
when Θ1 > Θ2: Q = V * ρ2* (hT1-hT2), Q☼= 0
when Θ1< Θ2: Q☼= V * ρ2* (hT2-hT1), Q = 0
The electronic unit of the heat meter performs all necessary measurement and data storage functions. The unit:
• Measures heat energy and determines overload characteristics;
• Calculates and stores maximum values;
• Stores data necessary for reports for a day set yearly and monthly;
• Measures the consumption under tariffs;
• Stores 36-month values, including the calculated energy, volume, and tariff register;
• Determines errors;
• Displays values, parameters (selectively) and error codes;
• Performs test and service functions.

INSTALLATION PROCEDURE
General Requirements
Prior to installing the meter:
• Check the complete set of the meter with that specified in the technical documentation;
• Check for any visible mechanical defects;
• Check the configuration of the meter and change it, if necessary.
The meters may only be installed by qualified specialists in accordance with the requirements of this document and the meter
installation design.
DO NOT lay signal wires closer than 2 in. (5 cm) from power cables or cables of other devices.
Checking the Meter Conguration
Prior to installing the meter, verify that its configuration complies with the requirements for the specific facility and change it,
if necessary (if the meter is in the transport mode, the configuration can also be changed by the press-button or with
HEAT3_service configuration software, without damaging the meter structure or seals). The following parameters are verified
(the factory settings for the meter are their standard ones):
• Whether the meter is intended to be installed in a supply or return pipe;
• Whether the meter is intended to measure heat energy or heat and cooling energy;
• Energy measurement units;
• Displayed energy resolution (point position);
• Whether the tariff registers are activated and the functioning conditions of the tariff registers;
• Whether the pulse inputs are activated, their purpose, pulse values, initial values of their volume registers, and volume
register resolution (point position);
• Whether the pulse outputs are activated, their purpose, pulse values, initial values of their volume registers, and volume
register resolution (point position);
• The reporting year and month date;
• The subscriber number;
• The internal clock time;
• M-Bus interface addresses and communication speed.
OTE:NThe transport mode will turn off automatically (the possibility to change configuration parameters will be turned off)
when the meter starts operation and the volume integrator has accumulated more than 1 litre. For meters powered
externally without a battery, the meter will remain in transport mode if the meter is not powered, but there is flow.
The transport mode can also be turned off using the button (like turning on Test Mode) and with the HEAT3_service
configuration software
Procedure for Checking the Meter Configuration
If the meter is in the transport mode, its display is off in the stand-by state. The display is turned on by pressing the button
and, as long as the meter is in the transport mode, it will turn off after 5 minutes (in the normal operation mode, the display is
constantly on and constantly shows the value of measured energy).
To review and change of the configuration, press and hold down the button until INF turns on at the bottom of the LCD. To
select a parameter, press and release the button then change the parameter, if necessary.

Changing the Meter Configuration
The parameters marked in “Procedure for Checking the Meter Configuration” on page9 can be changed using the
configuration program HEAT3_service (or with buttons, if the meter is in transport mode). If the transport mode is turned off
in the meter, to change parameters (except type of energy measurement, measurement units and installation place), the slot
SERVICE should be opened at the back of the electronic unit by breaking the partition and to short-circuit the contacts inside
(TEST indication will turn on). By short-circuiting the contacts repeatedly, the configuring function will be turned off. After
configuration, the slot must be sealed with a sticker seal.
Installation Procedure
Page 12 November 2020HYB-UM-03193-EN-02

Electrical Wiring
If the meter is to be powered from an external 230V AC or 24V AC/DC source, the cable of the meter intended for the purpose
and respectively marked is connected to the respective source (see "Transportation and Storage" on page 30).
If the meter is completed with wire interfaces or the Pulse Input/Output function, the cables intended for the purpose and
respectively marked are connected to the respective external appliance (see "Transportation and Storage" on page 30).
Mounting the Calculator
Mount the electronic unit (calculator) of the meter in a heated room. The temperature of the working environment should not
be higher than 131° F (55° C). It may not be exposed to direct sunlight.
No special requirements are established for the free space around the meter. It is important that nearby installations or
structures do not rest against the housing of the meter, do not hinder the laying of cables and reading of data on the display.
Install the meter at a safe distance from other devices emitting heat or strong electromagnetic field (in order to prevent the
disturbance of its working environment conditions).
The electronic unit is mounted on an auxiliary holder. It can be oriented in the required direction at an angle of each 90:
The possible ways of the mounting of the electronic unit (auxiliary holder):
Direct mounting on the housing of the flow sensor, by turning each 90° only when the flow temperature does not exceed
194° F (90 °C):
On a wall:
In the electrical equipment cabinet, on a standard DIN rail:
Installation Procedure
Page 13November 2020 HYB-UM-03193-EN-02

IMPORTANT
DO NOT attach the electronic unit directly on the wall because there is a risk that moisture may condense on the walls of the room or
the temperature of the surface of the wall may drop below 131° F (5 °C). Mount the unit to provide for an air space of at least 2 in.
(5 cm) between the unit and the wall surface.
Mounting the Flow Sensors
The installation and overall dimensions of the primary flow sensors are provided in "Dimensions" on page 32.
When installing in a pipeline, the following lengths of straight sections are required for sensors connected by flanges DN65,
DN80, and DN100: upstream of the sensor, at least 5 pipe diameters; downstream of the sensor, at least 3 pipe diameters. No
straight sections are required for flow sensors of other connection types either upstream or downstream of the meter.
Install flow sensors in pipelines as far as possible from pumps, partitions, and elbows.
Flow sensors may be installed horizontally, vertically, or in a slope. Mandatory condition: in the Operating Mode, the pipe must
have a pressure of not less than 30 kPa and the pipe must be fully filled with water.
In respect of the longitudinal axis of the pipe, flow sensors with the connection type G3/4, G1, or DN20 may be mounted at
any angle. See (a) in Figure 1; flow sensors of other connection types can be mounted in the positions specified in (b) in
Figure 1; (it is not allowed when the flow sensor cover is oriented in a vertical position).
(a) (b)
Figure 1: Allowed installation positions of the flow sensor
The flow direction and the direction of the arrow on the flow sensor must coincide. The flow sensor can be installed either on
the supply or return line, depending on the indication on the label of the meter. Prior to installing the sensor, the pipeline of
the heating system must be flushed at the place of the installation of the sensor.
In order to avoid stresses in the pipelines, the distance between the flanges at the flow sensor installation place must
correspond to the total length of the sensor with regard to the thickness of gaskets. Select the flow sensor installation place as
far as possible from potential sources of vibration (for example, pumps). When installing the sensors, make sure the gaskets do
not protrude inward the pipeline. Do not lay the wires of the flow sensor closer than 2 in. (5 cm) from power cables or cables
of other devices.
Installing the Temperature Sensors
Install the temperature sensors with their placement heads upward, perpendicular to the pipe axis or at an angle of 45° to the
fluid flow direction so that the sensing element is immersed in the medium being measured at least to the pipe centerline
(see the figures in "Sealing the Meter" on page 51). When the meter is fitted with flow sensors with flanges G3/4, G1, and
G1-1/4, one temperature sensor is installed in the housing of the flow sensor. DO NOT lay the wires of the temperature sensors
closer than 2 in. (5 cm) from power cables or cables of other devices.
Checking Installation and Parameter Settings
If the meter (calculator, flow and temperature sensors) is installed correctly, when there is flow, the display of the meter
represents the flow and temperature readings. If the readings of the measured channels are not displayed, check the
installation of electrical circuits.

OPERATING PROCEDURE
Control Button
The representation of measured and information data on the display is selected by the control button located on the upper
part of the electronic unit.
Control
Button
Representation of Data
Data are displayed on a liquid crystal, 8-digit display with special symbols for the representation of parameters, units of
measurement, and Operating Modes:
When the flow is flowing in the right direction, it is represented by a right arrow ; when the flow flowing in the opposite
direction, it is represented by a left arrow . When there is no flow, no arrow is displayed. The purpose of other symbols is
described in “Menu Structure” on page16.
This following information can be displayed:
• The values of the integral and instantaneous measured parameters when the symbol INT is displayed,
• The data of monthly archives and data of the reporting day when the symbol BIL is displayed,
• Information on the configuration of the device when the symbol INF is displayed.
The consumed heat energy is displayed constantly. Other data are represented on the display in a sequence with the use of
the control button.
When the meter is configured for the installation in the supply line, the symbol is displayed; when the meter is configured
for the installation in the return line, the symbol is displayed.
The symbol is shown when there is a significant meter operation error (due to which the summing-up of energy or normal
working time is suspended). For the error code, see the LCD menu item 1.12 in “Menu Structure” on page16.
