Product description 

Fire-fighting ultrasonic flowmeters are mainly used in liquid media that need to measure flow, such as fire-fighting pipelines. The principle of ultrasonic flowmeters is to use the ultrasonic transducer to send and receive the difference in the propagation time of ultrasonic waves in downstream and counter-current media to measure the flow rate of the media. The ultrasonic velocity in the flow direction will increase, and the ultrasonic velocity in the counter-flow direction will decrease, and the same propagation distance will have different propagation times. According to this time, the flow velocity is obtained, and then the flow velocity is calculated by the flow velocity.

Features 

1. The meter body of the fire-fighting ultrasonic flowmeter is a straight-through integrated structure and is made of precision casting technology.

2. With hollow structure, the real water flow is unobstructed, which is especially suitable for China's heating water quality and working condition requirements, and the pressure loss is smaller.

3. It is completely unaffected by impurities, chemical substances and magnetic materials in the medium, and the operation is very stable and reliable.

4. The measurement structure has no moving parts, never wears out, and the measurement accuracy is not affected by the service cycle.
