1.2.9 Pulse or digital output signal.
An output can work in different modes: frequency, pulse or digital. Output signal can be in two logical
states: "closed"/"opened". It is passive output of open collector type.
There are two pulse outputs for T version with 2-wire connection type. One of them corresponds to
NAMUR standard.
For "Frequency output" mode signal frequency is proportional to currently used variable. The following
values can be used as variables: volume flow rate, volume flow rate under normal conditions, mass flow rate,
absolute pressure, temperature.
Note: Hereinafter referred to as N.C.): - normal conditions (atmospheric pressure is 101325 Pa = 760 mm Hg.
and air temperature 273,15 K = 20° C).
Minimum and maximum values comply with:
FMIN = 0 Hz - minimum value of current variable;
FMAX = 1000 Hz - maximum value of current variable:
Typical pulse values m for gas and liquid measuring at maximum frequency of 1000Hz are specified in
Table.2.2.
Pulse value m can be calculated as follows:
m = Q’max / (3,6 * 1000 Hz), L (1.4)
where Q’max is maximum possible flow rate (see table 2.2) for this size of flow meter, m3/h.
For "Pulse output" mode every output pulse means exact value of currently used variable which is called
pulse value. Volume, volume under normal conditions or mass can be used as currently used variable. Pulse
value and minimum pulse length can be specified according to customer needs. Signal frequency for pulse
mode shall not exceed 500Hz.
For "Digital output" mode an output switches between "closed/opened" when instantaneous flow ("flow
switch" mode) or total volume/mass ("dosing" mode) reach specified limit value.
Dosing mode operating procedure.
1) resettable totalizer set to zero, digital output set to initial state. This state is taken as normal (basic).
Flow meter is ready to accumulate flow.
2) External automatic control device will turn the valve or pump upon output signal change. Flow meter
counts amount of medium. External automatic device can stop flow counting if there is no technological need.
3) digital output change the state once the specified limit is reached. External automatic device stops the
flow according to output state, switch the flow or change tare, if required.
4) Simultaneously with the step 3, the timeout timer is started in milliseconds (from 1 to 65535) specified
in register 40011. At the end of the timeout, go to step 1 of the algorithm.
In any mode allowed external voltage for pulse (digital) output shall be 5V to 27V. Maximum current
shall be 50 mA. Recommended resistance of load resistor Rload shall comply with:
(U-1)/0,04<Rload. < (U-1)/0,02, Ohm, (1.5)
where U – external voltage, V.
Connection diagrams for recorder are shown in Appendix B.
All modes 0...11 are implemented on the same terminals so that only one mode can be applied at a
time. Modes and maximum/minimum values can be adjusted via Modbus or flow meter keyboard. For more
details see Appendix G.
1.2.10 Analog (current) output signal.
Current in the circuit lies within 4-20 mA range and varies linearly with currently used variable. The
following values can be used as variables: volume flow rate, volume flow rate under normal conditions, mass
flow rate, absolute pressure, temperature. Modes can be adjusted via Modbus or flow meter keyboard. Values
for 4 mA and 20 mA can be adjusted via HART. For more details see Appendix I.
Analog signal is not available for transmitter of C version.
For T version with 2-wire connection the output signal lies in the 4-20mA range and corresponds to
NAMUR standard.
By default for EV-200 and EV-200-PPD 20mA corresponds to the max flow Qmax for the DN as
specified in the tables 1.3 and 1.4.
For EV-205 the current value of 20mA corresponds to 28 cbm/h for liquid and 210 cbm/h for gas and
vapour. 4mA corresponds ot zero flow. Values for 4 mA and 20 mA can be adjusted according to specific needs.
For guaranteed operation of the current output, the total resistance of the current output circuit R1 must
correlate to the following:
R1 ≤ (Uп- Ui) / 0,024, Ohm, (1.6)
where Up – power supply unit voltage, V.
Ui = 12 V for standard and extended versions of the transmitter,
Ui = 15,5 V for version with 2-wire connection scheme;

EMIS-VIHR 200
OPERATION MANUAL
www.emis-kip.ru/ru/prod/ev200 18
For general industrial version and for explosion-proof versions Вн, РВ the voltage at the terminals of the
current output should be in the range from 12 to 27 V.
For explosion-proof versions ЕхВ, ЕхС, ЕхiaВ, ЕхiaС, РВI, РО the voltage at the terminals of the
current output should be in the range from 12 to 25,3 V.
1.2.11 Digital output signals.
Modbus is the main digital output signal. It complies with EIA/TIA-422-B and ITU V.11 requirements,
provides data transfer through Modbus RTU (Modicon Modbus Protocol Reference Guide P1-MBUS-300 Rev.
G) and provides network connection and measured data transfer.
ModBUS transfers the following data to Windows PC with installed EMIS-Integrator software (supplied
with flow meter upon request and available on our web-sitewww.emis-kip.ru):
-flow tube diameter, mm;
-flow range, m³/h;
-flow meter serial number;
-instantaneous flow during damping time, m³/h;

-temperature and pressure from connected sensors;
-adjustable parameters of flow meter.
Wiring diagram is shown in Appendix B.
ModBUS is not available the transmitter with a two-wire connection scheme.
Additional digital output signal complies with HART TM standard.
Adjustment of the first, second, third and fourth variables for HART output is made via separate
Modbus protocol. Adjustment of any other parameters for 4-20 mA output is made through modem or
communicator.
