Application Notes

EAP-031044

A positive displacement flowmeter is used to measure the flow of a variety of different viscosity liquids. The flow rates range from 0-5 gpm to 0-50 gpm. The flow rates relate to a DC pulse frequency from a proximity sensor of 0-1.2 Hz to 0-12.0 Hz.

I need one frequency to analog transmitter that will provide a 4-20mA DC signal under both conditions and for any other frequency range which may occur in this application.

The M-System model M2XPA frequency to analog transmitter would be a perfect fit for this application. Its built-in sensor excitation power supply eliminates the need for additional equipment. The M2XPA can be programmed via model JXCON, JX configurator connection kit to accept frequency ranges up to 100 kHz with full scale spans as low as 0.01 Hz. A large variety of input types including RS-422 line driver pulse is available.

The M2XPA can be also programmed in detecting level, zero and span, sampling time, output type and its range, low-end cutout and so on.
