Programmable flow rate transmitter CP420L & CH420L

The electronic transmitters CP420L and CH420L are designed to work with TECFLUID’s volumetric counters COVOL and turbines. The instruments are supplied already configured for the type of input. The circuit is based on a microprocessor that, in function of the pulses per liter programmed, calculates the flow rate and totalizes the volume that flows through the meter and shows these values on a local indicator. The CH420L differs from CP420L in that it is also HART protocol compatible.

Technical specifications:

Operates with volumetric counter COVOL and turbine TM-44

Power supply

2 wires, by means of the loop current.

The instrument has a protection diode to avoid damage if the power supply is connected with inverted polarity.
