product overview
Industrial and commercial ultrasonic flowmeter is a fully electronic instrument that adopts new ultrasonic technology. It has many advantages such as small size, simple structure, no movable parts, good long-term measurement stability, wide range ratio, etc. Its measurement performance is at the international leading level.
Working principle
The industrial and commercial ultrasonic flowmeter calculates the gas flow rate V by measuring the time Tup for the upstream transducer to send ultrasonic waves to the downstream transducer, and the time Tdown for the downstream transducer to send ultrasonic waves to the upstream transducer, and then calculates the gas flow rate based on the cross-sectional area of the flow channel.
Main advantages
Measurement advantage
1. Ultra high sensitivity: capable of detecting subtle gas flows
2. Wide range ratio: The maximum range ratio can reach 260:1
3. High reliability: no moving parts, long-term operation is more reliable and there is no loss of measurement accuracy
4. Strong anti-interference ability: digital measurement signal output, not affected by magnetic field interference
5. Temperature compensation: Equipped with a built-in temperature sensor, it can output the accumulated volume after temperature compensation
Gas safety
● Reverse flow: The meter can detect reverse flow and determine that the meter is installed in reverse, and can automatically close the valve
Abnormal small flow: The meter detects continuous small flow to prevent gas leakage and can automatically close the valve
Installation and disassembly inspection: If the meter detects air intrusion, to ensure gas safety, it can report to the system and automatically close the valve
High temperature detection: If the temperature detected by the meter is higher than the high temperature alarm threshold, the valve can be automatically closed to ensure gas safety
● Water intrusion detection: If the meter detects water intrusion, it can automatically close the valve to ensure the safety of the pipeline network
● Constant flow alarm: When the meter detects a constant flow alarm, to ensure gas safety, it can report to the system and automatically close the valve
