MAIN FEATURES

Flowcomputer

Transus Instruments in partnership with GGS has developed a seamless interface to the GGS model SFC3000 Flow Computer. In combination with the SFC3000, the condition of the meter and its application can be monitored remotely. Using the web interface of the SFC3000, the metering system can be accessed remotely on any PC or even mobile phone. User-friendly screens have been developed to enable quick and easy monitoring of the system. Hourly, daily and weekly averages of diagnostics can be compared to known good conditions, to enable early detection of possible drift or indication of potential problems.

Difficult Applications   

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.

Harsh Environment 

The UIM Series epoxy coated aluminium alloy electronic housing, rated to IP66 and NEMA 4X, is designed to be used outdoors in almost any environment. A stainless steel version of the electronic housing is also available, suitable for offshore installations. The ultrasonic sensors have all titanium wetted surfaces and are designed for process gas temperature from -30°C (-22°F) to+80°C (+176°F).

Accurate and Fast Response 

The UIM Series have three or four paths as standard. This results in a stable, accurate flow reading over the full range of flow, pressures and gas composition. The Broadband Continuous Wave signal processing allow more than one path to be interrogated simultaneously avoiding the slow response that is the hallmark of other multi-path meters.

Pressure and Temperature 

For applications requiring integrated volume conversion, the UIM Series flowmeter is capable of interfacing directly to pressure and temperature sensors. The standard volume flow is calculated using the traditional volume conversion equations using fixed parameters for gas composition.

Versatile I/O 

The UIM Series comes standard with the Pulse/Frequency output and a USB port for commissioning and field service. Optional I/O Boards can provide an isolated RS485 and two additional isolated Pulse-Frequency outputs and 4-20mA/HART.   

Intrinsically Safe 

The UIM Series are Intrinsically Safe (ATEX/IECEx Intrinsically safe for zone 0). Installation is simple and economical as no special precautions are required for wiring and housing. The versatile keypad and display can be accessed in a hazardous area without special precautions, so start-up and diagnostic monitoring is quick and 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.   

Simplified Design 

With only a single circuit board having all circuits on-board, the UIM Series is extremely simple by design. The two optional expansion boards are fitted directly on the main board. International Approvals The UIM Series complies with IECEx as well as ATEX and CSA requirements for intrinsic safety. Metrological approvals include MID 2014/32/EU, OIML R137-1&2 (class 0.5) certification and AGA-9 compliance. See the respective data sheets for a full list of certifications and approvals.
