Roots Flow meter

1. Measure with high accuracy 2 Small pressure lose 3. Abount of variration 4. Excellent durablity

F Series Roots flow meter

Introduction: F series Roots flowmeter derived from the technology trade between TOKICO Co., Ltd. Japan and Endurance Co. in the end of 1990s, which is advanced technique for China in that times. Roots flowmeter is a highly accurate metrological instrument to continuously or instantaneously measure the flow rate of fluid in pipeline, which mainly composed of measuring unit, a pair of Roots rotor, transmission components and registry unit. It is of high accuracy, large flow rate, steady operation, none pulsating flow, low noise, good reliability and is able to remote monitor with 4-20mA signal.

Main technical parameters:

Nominal diameter (mm): DN15~300

Accuracy: ±0.2%,±0.3%,±0.5%

Flow range (m3/h): 0.5~1200
