Application Notes
EAP-031085

I measure water flow based on a level signal in a waterway. Can I have a transmitter which provides an output linear to the flow? The level signal is transmitted by a potentiometer with a resistance value linear to the level. MS Word


As flow meter to detect water level change and measure flow, there are orifice, weir, parshall flume, etc. and some are equipped with a potentiometer to output for remote transmission. In this case, the scale of the flow indicator on site is disproportional, however the potentiometer resistance value is linear to the water level. To indicate this signal as flow, the scale of the indicator is disproportional.

To convert into a signal linear to the flow, our Field Programmable Potentiometer Transmitter model M2XM is suitable. The M2XM is very convenient in programming input-output characteristics freely, such as measuring a liquid measure by a tank level in a spherical tank, or converting a revolution into a linear signal, etc.

Moreover, in case the output characteristics are not fixed when determining the specifications, PC Configurator Software model JXCON is useful to set/change the specifications on site easily after installation.

M-System has flexible solutions to meet your specific application and requirements. Consult our Signal Conditioners Data Library.
