An optional gauge pressure sensor is available on the secondary output model "-P". ![]() The FLR-1600A water meter provides data on the flow rate and temperature via the standard local display and the RS232 serial output. These flowmeters are available in ranges of 500 microliters per minute full scale to 10 liters per minute full scale. The FLR-1600A Series was designed with deionized water in mind. The unique method of flow detection allows the meter to measure extremely low flow rates at an affordable price. The FLR-1600A Series is a Volumetric Water Flowmeter. It uses the same technology as the laminar gas mass flow and volumetric flow meters, FMA-1600A and FLV-1600A. OMEGA™ flow meters measure differential pressure within that laminar region to achieve a turndown of 50:1 typical and the accuracy is ☒.0% of full scale. Differential pressure measurement, across a laminar flow element, results in a flow meter that is inherently linear. Those technologies define the types of Mass Flow Controllers, and they include differential pressure (ΔP), differential temperature (ΔT), Coriolis, Ultrasonic, electromagnetic, turbine, etc.The OMEGA™ Series FLR-1600A and FLV-4600A series flowmeters and controllers use two of the best studied physical properties of liquids to measure flow: Pressure and Viscosity. There are many different technologies which can help to measure the flow of the fluids and eventually help in controlling flow. High pressure may cause erratic flow rates. Low pressure will starve the MFC of fluid and cause it to fail to achieve its setpoint. Mass flow controllers require the supply gas or liquid to be within a specific pressure range. ![]() ![]() The flow rate is specified as a percentage of its calibrated full scale flow and is supplied to the MFC as a voltage signal. The MFC is fitted with a closed loop control system which is given an input signal by the operator (or an external circuit/computer) that it compares to the value from the mass flow sensor and adjusts the proportional valve accordingly to achieve the required flow. A digital flow controller is usually able to control more than one type of fluid whereas an analog controller is limited to the fluid for which it was calibrated.Īll mass flow controllers have an inlet port, an outlet port, a mass flow sensor and a proportional control valve. The device will then control the rate of flow to the given setpoint. The MFC can be given a setpoint from 0 to 100% of its full scale range but is typically operated in the 10 to 90% of full scale where the best accuracy is achieved. ![]() A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates.
