Frequency Converter

The FM-1D/K is a µP-controlled, frequency-to-current converter and flow rate indicator. It converts input pulses to an analog current signal proportional to the instantaneous flow rate. Equipped with a numerical display on the front, it converts registered pulses into:

• Consumption reading (pulse totalizer) 
• Flow rate indication
• Output pulses with different pulse value and
• Normalized output current

You can also use the FM-1D/K for on-site display of flow rate and current counter reading, as well as remote transfer for apportioning, process automation, display of flow rate and current counter reading.

Benefits to you

• Accommodates a wide range of pulse inputs
• Identifies reverse flow
• Indicates local instantaneous flow rate, consumption reading and configuration data
• Retains data by non-volatile memory, in case of power failure
