1Safety Instructions
Danger to life, risk of injury and damage to material or property.
Read the Operating Instructions carefully before initial operation.
Observe general safety precautions as well as those included in various sections of these Operating
Instructions
Hazard risks:
-non-observance of the Operating and Safety Instructions
-modifications to the device by the customer
-handling the device outside the specified operating conditions
-handling the transducers outside the specified operating conditions
-use of unsuitable power supplies and peripheral devices
-improper use of the device
Danger when installing the sensors in pressurized pipelines:
-sensors for use in pressurized pipelines are to be inserted or retracted only in depressurized con-di-
tions; non-observance may result in serious injuries to personnel
The pipelines for the gases to be measured must be insulated in such a way as to ensure that the elec-
tronic housing of the equipment does not reach a temperature higher than the maximum ambient temper-
ature specified above, taking into account radiation and convection heat.
1.1 Special Instructions
-When connecting mains adapters, pay attention to the mains voltage.
-When operating outdoors, it must be ensured that the housing cover and the cablebushing are
firmly screwed to the housing, otherwise protection class IP65 is not guaranteed.

2Initial Operation of the Measuring Device
For the installation and operation of the measuring system, the applicable national regulations for the in-
stallation and operation of electrical systems, as well as the general rules of technology and these operat-
ing instructions are decisive.
Galvanic isolation between power supply and analog output
ground analog output = ground housing
2.1 Pin assignment supply voltage
Pin1: ground
Pin2: V- (0 V)
Pin3: V+ (24 V)
2.2 Pin assignment analog output
Pin1: 0-10 V analog output
Pin2: analog output GND (for 0-10V resp. 4-20mA)
Pin3: 4-20 mA analog output
Pin4: not connected
Pin5: not connected
2.3 Device parameterization
The device can be parameterized via the user interface (see chapter 3) or the TCP interface (see
chapter 4).

3User Interface
The user interface consists of an illuminated 7" touch display, which is embedded in the housing.
After starting, the tab graph is displayed. At the top, you can switch to the respective tab by tapping on
the corresponding tab.
3.1 Tab Graph
Task: of the instantaneous values (textual and graphical) and the quantity counter. Locking and unlocking
option of the user interface.
In the Tab Graph, the measured values in the available graphs are displayed averaged over a period of
100 ms. 200 measured values of 100 ms each are shown, which corresponds to an observation period of
20 seconds.
The graph offers different views, which can be switched through in the following order by tapping on the
diagram itself.
common graph for flow, temperature, pressure, humidity1with separate Y-axes
graph for flow
graph for temperature
graph for absolute pressure
graph for humidity1
three separate graphs for flow, temperature, pressure and humidity1
Die unit of the flow value can be set in the Tab Settings (see chapter 3.3).
By tapping on the symbol or on the upper right edge, the interface can be locked or unlocked. To
unlock the security code, which is „71334“ by default, is required. It is recommended to change the
security code directly after initial operating (see AK command „ESCO“ in chapter 4.4.5) to protect the unit
against unauthorised access. The interface is automatically locked again after the set "Display switch-off
and TCP lock time" (see chapter 3.3 or AK command „EDTT“ in chapter 4.4.5) has expired.

3.2 Tab Control
Task: Starting and stopping the measuring function, resetting the quantity counter, restarting and
shutting down the unit.
In Tab Control the measurement can be paused. The graph is no longer updated when the measurement
function is stopped; the last measured value is permanently displayed. The measurement data via TCP
interface also no longer change, the last measured values are always transmitted. The analog output is
also frozen at the last value.
The quantity counter (forward, as well as backward) can be reset to 0 by tapping the "Reset" button.
To restart or shut down the unit properly, use the buttons in the lower section. It is always advisable to
shut down the unit properly to avoid loss of data (settings, quantity counter, ...).

3.3 Tab Settings
Task: Displaying and changing device parameters.
In Tab Settings, the following settings of the device can be changed:
Device description
The device designation is a freely selectable name with a length of 15 characters for designating
the measuring point.
Display orientation
Orientation of the display standard or rotated by 180°
Display auto off
Time in seconds until the display is automatically locked after the last touch. This time period is
also used for the TCP lock (see also chapter Fehler! Verweisquelle konnte nicht gefunden
werden.).
Device unit
Flow unit switchable between kg/h, Nm³/h and m/s.
Damping (GUI & AK)
Damping in milliseconds for the graphic interface and the values via AK protocol.
Offset volume flow
Freely selectable offset for the value of the flow in the set unit.
Offset pressure
Freely selectable offset for the absolute pressure sensor.
Offset temperature
Freely selectable offset for the temperature sensor.
Offset humidity1
Freely selectable offset for the humidity sensor.
TCP address
IP address for TCP interface. Input in the usual format of IPV4 addresses.
A restart of the unit is required to apply the change.

TCP port
Port address for TCP interface.
A restart of the unit is required to apply the change.
Analog out - Start value
Start value of the analog output in the set unit. The start value must be smaller than the end
value, otherwise the value at the analog output is invalid.
Analog out - End value
End value of the analog output in the set unit. The end value must be greater than the start value,
otherwise the value at the analog output is invalid.
Analog out - Mean Type
Type of averaging of the analog output. Arithmetic mean value or moving average value in the set
damping time (see „Analog out - Damping“ here in this chapter).
Analog out - Damping
Damping in milliseconds for the analog output.
Standard density
Standard density of the gas to be measured - is required for the calculation of the mass flow.
Standard pressure
For Höntzsch, the standard conditions are 294.2 K (+21 °C / +70 °F) and 1014 hPa (14.7 psia).
Any standard base can be set via the parameters standard pressure.
Input in hPa
Standard temperature
For Höntzsch, the standard conditions are 294.2 K (+21 °C / +70 °F) and 1014 hPa (14.7 psia).
Any standard base can be set via the parameters standard temperature.
Input in °C
Impact of humidity1
Percentage influence of the humidity value on the measured value.
