LB70 spinning cup type current velocity  flow meter

Introduction

LB70 spinning cup type flowmeter is a universal type meter in river hydrology test to measure mean flow rate of scheduled testing point in rivers, lakes, reservoirs, channels and so on. Section flow can be calculated by each point flow rate and average of all sections.

Main Technical Parameter
