TrueShot™ by Transus
Ultrasonic Flow Meters

Using patented Broadband Continuous Wave – BCW™ signal processing and high efficiency titanium transducers TrueShot UIM Meters provide reliable and precise ultrasonic flow measurement even in the most extreme applications.

Ultrasonic Flow Meters

TrueShot meters are available in single, dual three path, four path and customized configurations, ideal for a broad range of applications from upstream to downstream.

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.



The UIM-4F for Custody Transfer metering of natural gas and other gases.



The UIM-3/3F for Industrial Metering-fiscal accuracy at an economical cost.


UIM-4F Duo

Two independent accurat fiscal flow measurements in a single flowmeter body. 


UIM-1 and UIM-2

The UIM-1/UIM-2 for flare gas, vent gas, fuel gas, process gas and biogas.

Titanium Transducers

The efficient design of the ultrasonic transducers allow them to operate at 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. Optionally retractable UIM Series Transducers are suitable for pressures up to 153 bar (2250psi). Titanium ultrasonic sensors coupled with broadband continuous wave processing can measure the most challenging applications such as wet and dirty gases, varying gas compositions and attenuating gases. The combination of the transducers and the Broadband Continuous Wave processing is also resistant to noise.
