UIM features

Titanium Transducers
Rugged and efficient

The very efficient design of the ultrasonic transducers allow them to operate at the very low transmitting voltage of 3.6V compared to tens or even hundreds of volts required by other manufacturers. All wetted surfaces are metal for the harshest conditions. The optionally retractable UIM Series Transducers are suitable for pressures up to 153 bar (2250psi). The titanium ultrasonic sensors are remarkably  efficient and coupled with the Broadband Continuous Wave processing can reliably measure the most challenging applications such as wet and dirty gases, varying gas compositions and attenuating gases. The combination of the efficient transducers and the Broadband Continuous Wave processing is also resistant to noise.

Intrinsically Safe

The UIM Series are Intrinsically Safe (ATEX/IECEx Intrinsically safe for zone o). Installation is simple and economical as no special precautions are required for wiring and housing. The versatile keypad and display can be simple. Field wiring may also be accessed without the need to shut down the meter and lose measurement data. The low energy levels inherent in Intrinsically safe design result in low operating power (<<1 watt), making the UIM Series ideal for solar or battery power applications.
