  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.
