Functional specifications

Each communication specification has the following functions.

Simulated output flow rate output (volume flow rate, mass flow rate, volume flow rate under normal/standard conditions, energy)

Temperature output (for built-in temperature sensor type)

Buffer time constant 0~200 seconds (63% response time)

Delay time: 0.5 seconds

Analog output circuit time constant: 0.3 seconds

If there is a CPU or EEPROM failure in the disconnect function, the analog output will exceed the upper limit (21.6 mA or above). The upper or lower limit (3.6 mA) can be selected through the switch

Or below).

Output that complies with NAMUR NE43 can be specified as optional.

Pulse output function (* 1) Pulse output: calibrated pulse, non calibrated pulse, frequency (number of pulses output per second at 100% flow or temperature)

Pulse frequency: maximum 10 kHz, maximum 1 kHz (Ta: -40 ℃~-50 ℃, suitable for optional code:/LAT)

Duty cycle: approximately 50% (Ta: -40 ° C~85 ° C)

Greater than 15% * 3 (Ta: -50 ° C~-40 ° C, applicable for optional code:/LAT)

*3: The duty cycle may vary due to factors such as ambient temperature, load resistance, frequency, etc.

Self diagnosis and alarm output

(*1)

If an alarm occurs (due to over range output signal, EEPROM error, vibration interference, blockage or bubbles causing abnormal flow), an alarm signal will be output.

If the instrument is equipped with a display, the NE107 category will be displayed together with the alarm number.

When an alarm occurs, the alarm signal output changes from OFF to ON or from ON to OFF.

The alarm signal output mode can be selected through parameter settings.

Status output function (* 1) Flow switch: Based on the flow rate, temperature, and cumulative flow rate settings, the status output changes from OFF to ON or from ON to OFF

In the OFF state.

The state output mode can be selected through parameter settings.

*1: Choose any of these features.

Analog input Analog input 4~20 mA (passive)

Can input (* 2) temperature, pressure, density

*2: To ensure accurate temperature/pressure compensation, please refer to the "Installation Instructions" and carefully pay attention to the positions of the pressure and temperature measuring holes.
