PS-WKJ biological network flow meterAccording to the National Marine Monitoring StandardsGB 17378.7-2007Design and production are required to measure the filtration capacity of various plankton nets.

5Mechanical counter with reverse stop function, suitable for both horizontal and vertical trawling.

overall length205mm, impeller diameter75mm.

Counting the amount of filtered water:

V =πr²( b - a ) Rc

VFilter water volume,m³

r: Mesh port radius,m

b: Terminate reading

a: Initial reading

Rc: Rotor constant

PS-WKJDElectronic biological network flow meterThe design is mainly used for measuring the volume of water passing through plankton nets.

The design of electronic flow meters is mainly used to measure the volume of water passing through plankton nets.

6The LCD display shows the trawl distance in meters.

The amount of water can be easily obtained by multiplying the measured value with the area of the planktonic net.
Even under the influence of vortex flow from the front impeller, at low speeds（>0.1m/s）Under the condition of water flow, measurement can also be ensured Accuracy. Even in the presence of reflux, it will not affect the measured value.
The counter can be reset to zero by adjusting a knob.
This flowmeter is maintenance free, and the movable part is a replaceable impeller.

The built-in lithium battery can be used in continuous operation5Year.
