Indeed, an ultrasonic flowmeter works without moving parts or electrodes, and uses the speed of sound through a medium
Flowmax® instruments are suitable to measure nearly each liquid.
As long as soundwaves can travel through, the liquid properties, conductivity or presence of particles play no role.
When there’s flow, sound will travel faster from A to B and slows down from B to A.
The time-difference relates to the liquid speed.
Flowmax® measures this time-difference 250 times per second.
The raw measurement is then filtered according to your preferences and exported in a digital or analogue output.
Remember the days when a series of instruments was used to monitor your liquid-flow.
A PT100-sensor would indicate the liquid temperature.
Followed by a conductivity-measurement to follow general properties of the liquid.
Air- and gas bubbles are usually unwanted, therefore a detector would be installed in the line as well.
Maybe viscosity or concentration are of interest?
Well, there’s good news! All these functionalities are integrated in ONE sensor.
We hope you don’t mind that we designed it as a non-invasive system, just the body, nothing else is in contact with the medium.
Flowmax® measures flowrate as well!
All Flowmax® technology is developed by MIB GmbH and is subject to continuous improvement.
More than twenty years ago, Flowmax® made its entry in the highly dynamic environment of beer tapping system.
The challenges encountered there have lead to a robust sensor-design.
Typically, Flowmax® instruments have a plastic body which is the only wetted part of the instrument.
By separating the electronics from the sensor-tube, MIB GmbH created the basis of Flowmax® 242i Single Use flowmeter.
Until today, each instrument -including the Single Use type- uses the same proven technology.
Open bore, no moving parts, no electrodes or metals.
No internal gaps, seals or dead spaces, smooth surfaces.
Certified base materials, high chemical resistance.
Can be Gamma-irradiated.
Calibration data stored inside each measuring tube.
Customizable process connection integrated in the body.
