Flowmax 42i is a flow meter calculating the volume flow of liquids. Based on the ultrasonic technology Flowmax 42i is able to measure conductive and non-conductive liquids contact-free. Flowmax has no moving parts and is absolutely free of wear. The design of the pipe minimizes dead space over the whole geometry. All parts having contact with the medium are PE-HD or PVDF. Thanks to its technical properties 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. Flowmax is characterized by its high measurement accuracy and repeatability. Empty pipe detection is integrated. Optionally Flowmax has 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. The start signal can optionally be fed from the outside. A control signal for activation of the pump or valve control is also standard.

Flowmax 42i is suitable for operation with piston diaphragm and peristaltic pumps.
