Flanged Ultrasonic Flowmeter GTTFF |
Series GTTFF Flanged Transit Time Ultrasonic Flow Meter uses transit-time ultrasonic technology in which
the signal is transmitted and received alternately between two flow sensors and the “time of flight” determines the
flow rate.
Applications include both commercial and consumable water measurement.
Long-term stability and a wide measurement range make it possible not only to measure water consumption,
but also to monitor systems for water leakage.

Features 1. Calibrated in manufacturer's lab, field setup is unnecessary. 2. Measurement is independent of fluid nature with wider applications than magnetic meters. High temp. type can be suitable for high temperature of -40°C ~150°C 3. Re-calibration or maintenance is easy, no processing interruption (just plug out the inserted transducers from pipe line, when re-calibration or maintenance is finished), can be hot-tapped. 4. Remote operation by the wireless handheld operator. No matter the pipeline in high altitude or underground, users can install or adjust the transducers more convenient. 5. The wireless handheld operator has wireless remote reading function and it also can operate the meters instead of panel operations. 6. Built-in large capacity memory and USB data download function. The downloaded data can be opened by EXCEL directly. 7. The heat measurement function by configuring with paired Pt1000 temperature sensors. Applications l Water (Hot water, Cooling water, Potable water, Sea water etc.) l Petroleum products l Chemicals, including alcohol, acids, etc l HVAC, energy measurement system l Beverage, food and pharmaceutical processors l Secondary sewage, waste treatment, etc. l Power plants (nuclear power plants, thermal & hydropower plants), heat energy boiler feed water. l Metallurgy and miming applications l Pipeline leak detection, inspection, tracking and collection l Network monitoring |
