The flowmeters and controllers of the FLR-1600 and FLV-4600 series use two of the best studied physical properties of liquids to measure flow: Pressure and Viscosity. Differential pressure measurement, across a laminar flow element, results in a flow meter that is inherently linear. OMEGA™ flow meters measure differential pressure within that laminar region to achieve a turndown of 50:1 typical and the accuracy is ±2.0% of full scale. It uses the same technology as the laminar gas mass flow and volumetric flow meters, FMA-1600 and FLV-1600. There are no moving parts to wear out.

The FLR-1600 Series is a Volumetric Water Flowmeter. The unique method of flow detection allows the meter to measure extremely low flow rates at an affordable price. The FLR-1600 Series was designed with deionized water in mind. These flowmeters are available in ranges of 500 microlitres per minute full scale to 10 litres per minute full scale. By placing the battery pack option on the FLR-1600 Series, it can function as a portable water meter for spot check or calibration.

The FLV-4600 Series Water Flow Controller uses a proportional valve coupled to a flowmeter body creating a unique in-situ closed-loop flow controller system. Measurements are taken within the laminar region of the flow meter and the integral PID controller positions the valve according to the flow set points. The controllers can accept an RS-232 or the 0-5 Volt control input signal depending on what is preferred. Independent of the set point voltages, the controllers can be configured for single or dual output of the same or different voltages and/or different parameters such as temperature and flow. This is possible because of our laminar flowmeter design that incorporates solid-state Differential, Absolute Pressure, and Temperature sensors to determine flow in an inherently linear system. The result is a fast responding linear flow meter with multiple outputs. All these parameters are simultaneously visible with our dynamic display that includes a push button operator interface. Water flow controllers are available from 50 millilitres per minute full scale to 500 millilitres per minute full scale.
