Ultrasonic Level Transmitter Microflex D

The Microflex-D from Hycontrol is a compact, non-intrusive, loop-powered ultrasonic level transmitter for continuous measurement of liquids. Microflex-D does not compromise on quality and provides effortless and intuitive operation together with easy and flexible mounting. 

Microflex-D’s high chemical compatibility and measuring range of either 8 metres (Microflex-D) or 12 metres (Microflex-D ER) makes it appropriate for applications in a wide range of industries.

 The Microflex-D emits an ultrasonic pulse which is reflected from the surface of the liquid being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false echoes. An automatic sensitivity control allows the unit to dynamically adjust and improve the received echoes to achieve the best possible measurement accuracy
