Advanced flow meter devices play a vital role in utilities, enabling precise monitoring and control of fluid and air flows. They allow for the accurate measurement of flow rates, enable efficient process optimisation, enhance the safety of operations, and are key to optimising resource allocation and reducing waste.

For more than 50 years, AMS has been supplying instrumentation, calibration equipment, software and controls to all utilities in Australia.

Their latest model, the FCI ST50 meter, is a compact, lowcost solution for accurate, repeatable flow rate measurement of air, compressed air or nitrogen. This insertion-style flow meter has no moving parts and is available in probe lengths for installation into pipe diameters from 63 to 610mm.

It is easily connected into the pipe via a 1/2 inch or 3/4 inch NPT compression fitting. ST51 uses constant power thermal dispersion drive technology, with a slightly heated sensor, which uniquely provides a subtle drying effect on the sensors that results in effective measurement in moist measurement applications.

The ST50 electronics are housed in a rugged, IP67-rated enclosure with dual conduit ports in either NPT or M20 threading. The instrument comes standard with dual 4-20 mA outputs – one for flow rate, and one for temperature. A 500Hz pulse output (for external totaliser) can be added as an option.

The transmitter and electronics can be integrally mounted with the flow element, or be remote mounted to best match your installation situation. The ST50 flow sensing element features precision, platinum RTD in small diameter, equal-mass, all-metal thermowells to provide superior accuracy, repeatability and fast response.
