TrueFlow TFM1 

Measure the TrueFlow

The TrueFlow TFM1 is a Coriolis Mass Flow Meter. It covers a large measuring range with high measuring accuracy and low pressure loss. The maximum measurable mass flow is 30 kg/h.

TrueFlow TFM1 is a stand-alone device suitable for use with our micro annular gear pumps or as a component in our Modular Dosing System MoDoS®.

The flexibility within the applications increases enormously, as the measuring range is significantly larger than that of comparable products.

In the longer term, it will be available in other sizes, alloy C, and further control options.
