Principle of Measurement

The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer, the sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted (Doppler frequency) from the transmitted frequency. The shift in frequency will be directly related to the speed of the moving particle or bubble. This shift in frequency is interpreted by the instrument and converted to various user defined measuring units.

There must be some particles large enough to cause longitudinal reflection – particles larger than 100 micron.

When install the transducers, the installation location must have enough straight pipe length upstream and downstream. Commonly, the upstream needs 10D and downstream needs 5D straight pipe length, where D is pipe diameter.

Features:

1.The system can be field configured to pipe sizes ranging from 40 to 4000mm.

2.For dirty liquids, a certain amount of air bubbles or suspended solids contain

3.Excellent low flow rate measurement ability, low to 0.05 m/s

4.A wide range of flow measurement, high flow rate can reach 12m/s

5.Automatically signal gain adjustment

6.Do not need to shut down the pipe flow when installing the transducers.

7.User-friendly configurations

8.4-20mA, totalizer pulse and relay alarm output

9.Accuracy: 2.0% Calibrated span

Approvals:II2G, ExdIIBT6, LCIE 09 ATEX 3088

Solutions:

For petrochemical plant and oil field, oily wastewater discharge, wastewater, sewage, oil drilling slurry, or all explosion-proof occasion of flow monitoring and measurement.

Notes:

When installing insertion transducer, Hot-tapped installation and demounted online, do not need to shut down the pipe flow when install the transducers.
