Ultrasonic Flow Meters at the Highest level – Flowmax 44i

Ultrasonic Flowmeters Flowmax44i - RST Electronic

Flowmax 44i is a flow meter calculating the volume flow of liquids.

Flowmax 44i is based on the ultrasonic technology. The model is able to measure conductive and non-conductive liquids contact free. This type of flowmeter has no moving parts and is absolutely free of wear and the design of the pipe minimizes dead space over the whole geometry. All parts having contact to the medium are PPSU. Flowmax is able to measure all kinds of liquids like: DI-Water, Body care liquids, Cosmetics, liquid food, and also aggressive and/or toxic acids and alkalis thanks to its technical properties. This type of flowmeter is characterized by its high measurement accuracy and repeatability. Empty pipe detection is integrated in this model. Optionally Flowmax have a PID controller function. The calculated flow is provided with a response rate of a few milliseconds on the outputs.

Flowmax has by default a preset quantity counter and the start signal can optionally be fed from the outside. A control signal for activation of the pump or valve control is also standard.

For operation with piston diaphragm and peristaltic pumps Flowmax 44i is suitable.
