Overview of Flowmax's main products: Flowmax54i, FM400i, Flowmax 42i, Flowmax 44i

Different sizes, shell materials, functions, with or without display.

A flowmeter for calculating the volume flow rate of liquids. Flowmax is particularly suitable for the automation of wet process equipment with dynamic processes.

Flowma has no moving parts and absolutely no wear. The pipeline design minimizes dead corners throughout the entire geometric structure.

All parts in contact with the medium are PFA (new Teflon), PSU (polysulfone), and PEHD (polyethylene).

Working principle of ultrasonic flow meter:

Based on the principle of phase difference, electronic devices, transmitters, and receivers are installed at both ends of the pipeline. When the medium flows, the ultrasonic waves sent and received will generate phase differences.

Countercurrent requires more energy than downstream, with two sensors installed in opposite positions to each other, one emitting signals and the other receiving ultrasonic signals.

If the medium is stationary, the ultrasonic signals received by both sensors are of the same phase and have no phase difference.

The flow of the medium will cause phase shift, and the phase measured by counter current and forward current is different. This phase difference is directly proportional to the flow velocity. The flow rate and the size of the pipeline can be used to determine the flow rate.
