Name：One-piece Tubular Ultrasonic Flow Meter
General Introduction：
Model：LRF-2000F
General Introduction：
LRF-2000F ultrasonic flowmeter is to connect the motherboard with a 20-wire, 4-key parallel port keyboard display and package it into a sealed case. The online display and operation sensor can be divided into external clamp-type inserted tube segment, which has the advantages of high precision, wide range, no pressure loss and simple installation.
