Introduction：
Modular type ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.
Transit-time measures the time differential between signals sent upstream and downstream. The differential is directly proportional to the velocity of the water. Transit-time meters are best used for measuring the flow of clean liquids and, as a result, are the most popular type of ultrasonic meter.
Feature:
*High Accuracy
Accuracy better than 1%
*Measure Range
Select different model sensors,can achieve DN15-DN6000mm pipe flow measurement
*High Reliability
Adopt low voltage, multi-pulse radiating circuit.Accuracy,Lifetime and Reliability are better.
*High Anti-interference
Adopt double balanced signal differential transmission, receiving circuit,
effective resist the drive,tower, Strong power lines and other source of interference.
*Powerful Memory Function
Automatic memory the cumulative flow of 512 days before, 128 months before, 10 years before. Automatic
memory the power-on and off of 64times before and the flow. Automatic memory the meter working condition of
32days before.
Application:
Chemical industry
City water supply
Waste water treatment
