Panametrics portable gas ultrasonic flowmeter Applications The TransPort PT878GC clamp-on gas flowmeter is a complete ultrasonic flow metering system for measurement of most gases, including: • Clamp-on unobstructed installation • Natural gas • Compressed air • Fuel gases • Erosive gases • Corrosive gases • Toxic gases • High-purity gases • Air separation gases • No wetted parts • No moving parts • No pressure drop • Sound speed output • Standard volumetric flow calculation • Small, lightweight and easy to use • Large, backlit LCD display • Rechargeable battery pack • Logs over 100,000 flow data points • Submersible package • 32 site

Portable flow metering at its best No pressure drop, low maintenance The TransPort PT878GC flowmeter is a highly versatile, selfcontained, portable transit-time system with options and accessories to meet a variety of gas flow measurement needs. Its compact size, lightweight, rechargeable battery pack, and universal power supply charger make it the ideal go anywhere flowmeter. Because the transducers clamp onto the outside of the pipe, they do not obstruct the flow inside the pipe. This prevents the pressure drops typically caused by other types of flowmeters. The TransPort PT878GC has no...

Quick and easy to use It’s possible to make the first flow measurement within minutes of opening the box—the TransPort PT878GC flowmeter is that easy to use. Input the site parameters, clamp the transducers onto the pipe, and adjust the spacing. No ancillary equipment is needed, and there’s no need to break into the pipeline. An experienced user can make scores of different measurements in a single day. The TransPort PT878GC flowmeter is ideal for all kinds of flow survey work. Built to be economical and stay economical To be of real value, a portable flowmeter must be as economical to own...

Submersible, rugged electronics housing This flowmeter is protected from the day-to-day rigors of industrial usage. The TransPort PT878GC is equipped with a rubber boot that provides protection against vibration and shock. The completely sealed housing and ports meet IP67 requirements, so the flowmeter will withstand submersion in up to 3 ft (1 m) of water for limited periods of time. It will continue to function safely even if it is dropped in water. 2. TransPort PT878GC AC charger 3. Clamp-on gas transducers 4. LEMO BNC transducer interconnection cable 5. Input/output cable 6.
