What's company of MIB?

Know How and development are the way to success

Experience for many years in development, production and industrial management for flow meters helped to create innovative solutions in ultrasonic flow measuring.

In association with our costumers in the different industrial branches we have developed products with the priority on following aspects:

• Our products shall work as a "Plug and Play" system which is easy to install  • and “Fit and Forget" solution, which is maintenance free  

• and also we want to help the costumer to minimize operating costs

Flowmax is a flow meter calculating the volume flow of liquids. Flowmax is particularly suitable for the automation of wet process facilities with very dynamic processes.

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

to the medium are PFA (New Teflon) or PVDF,  PSU (Polysulfon) PEHD (Polyethylene).

Flowmax 400i PFA

•If a display is needed, for higher temperature than 60°C and/or small footprint, use separate version 

•All wetted parts are made of cleanroom compatible PFA granulate in the injection molding process, under HP conditions. 

•DN 07; (0,03) 0,09 - 6,0 l/min; DN 10; 0,3 - 24 l/min; DN 15; 0,9 - 60 l/min; DN 20; 1,2 - 120 l/min. 

•Applications with smallest quantity detection up to 1l/h continuous flow in many applications in and outside the HP industry are installed in the field  •Very good results with oscillating liquid flows from diaphragm and peristaltic squeeze pumps 

•Very good results in combination with PID controlled valves or pumps due to very fast response times of signal processing and output. Reaction times of the valves of 0.2 sec are achieved!

Typical flow pattern pumping the liquid with peristaltic pump

If the flowmeter's reading is fast enough as with Flowmax (250 readings per second), the entire flow path is recorded and processed very excellent. This is valid for all processes with pumps and valves.
