Product Introduction
LS1206B propeller type current meter is a conventional universal instrument for measuring the flow velocity in hydrologic tests. It is used for measuring the average flow velocity in a period of time at a predetermined measuring point in the water section of rivers, lakes, reservoirs, canals and other rivers, as well as for measuring the flow velocity in pressure pipelines and some scientific experiments.
The LS1206B propeller flowmeter complies with relevant national standards such as GB/T 11826-2002 "Rotor flowmeter".
The LS1206B rotary propeller flowmeter is widely used in hydrological surveys, water conservancy investigations, farmland irrigation, runoff experiments, etc. It can also be used in industries or departments such as hydropower, environmental protection, mining, transportation, geology, scientific research institutes, and municipal engineering to monitor relevant flow velocity or flow rate.
Main technical performance and parameters
