Working principle and application of integrated ultrasonic flowmeter
LRF-2000F type ultrasonic flow meter is connected to a 20 line 4 motherboard parallel port keyboard keys display package to a sealedcasing, on-line display and operation. The sensor is divided into the outer clamping type, plug-in type, tube type. With high precision,measurement range wide, no pressure loss, easy installation and other advantages.
Applicable occasions:
1 drinking water, river water, sea water, underground water, cooling water, water, sewage;
2.Lubricating oil, diesel fuel,
3 chemical liquid
Working principle.
Battery tube flowmeter basic principle and types of ultrasonic wave in fluid communication when the load on the fluid velocityinformation. So by the received ultrasound can detect the flow rate of the fluid, thereby converted into flow. According to the detectionmeans, can be divided into propagation speed difference method, Doppler method, beam offset method, noise and associated methodof different types of ultrasonic flowmeter. Ultrasonic flowmeter is in recent years with the rapid development of integrated circuit technology began to apply a.
