Propeller flowmeterMain purpose and scope of application

The current meter is a kind of conventional universal instrument for measuring the flow velocity in the hydrometry. It is used to measure the average flow velocity in the period of time at the predetermined measuring points in the river, lake, reservoir, channel and other water cross sections, and can also be used to measure the flow velocity in pressure pipes and some scientific experiments.

The current meter shall comply with relevant national standards such as GB/T11826-2002 "Rotary Current Meter".

The current meter is widely used in hydrological testing, water conservancy investigation, 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.
