Low-end cutout for flowmeter signal

We use a 2-wire flow meter at field. We have some problems recently. Even the flow volume is zero, the indicator on the receiving instrument shows fluctuation and unstable.

Do you have any solution with any M-System transmitter? Furthermore, the flow meter doesn’t have square root extraction function, so please introduce a suitable transmitter with square root extractor.

Our current loop supply, the model M2DNY will meet your request. The M2DNY has square root extraction inside and has low-end cutout function. With the low-end cutout function, this unit forces its output into zero (0) at the output signal approx. 4-8% or less of full span. You can control low-end signal fluctuation on the display of receiving equipment.
