Universal Current Meter (CM-32)

AQUADATA CM-32

model Universal Current Meter used in

rivers, irrigation channels, seas,

in lakes, in water gutters, in drainage and evacuation

a flow rate used to measure water velocity in

measuring instrument.

Providing measurement even in the shallowest waters

as a complete set with different propeller variants

It is made. Universal Electronic Current Meter

as used in normal waters, in high waters

auxiliary measurement such as hanging train, donaw and cable car

with the help of a reel

Body

Made of stainless steel chrome steel.

With 2 precision bearings mounted on the shaft

the movement of the propellers is provided, the propeller

the sleeve is filled with oil and the plastic seal is mounted

to prevent water from entering the device

Pulse Formation with Magnet and Reed Contact

The magnet placed on the moving shaft,

fixed in body Reed In front of contact

a signal is generated in each pass.

Continuous pulsing every full revolution of the propeller

creation continues. The propeller is mounted

"non-friction" on shaft precision bearings

movement has increased the sensitivity of mulinenin. Reed

The contact mechanism is easy to change.

In shallow water up to a depth of 1 m.

it is possible to measure by entering the water. that

the pipe is placed on the bottom of the water. Current Meter device

are moved at regular intervals on the handle.

Roof-to-floor with ferrous floors is safe

they provide a sitting and the bottom is unnecessarily long

. Parallel to the flow of the sapphire

mini "direction indicator piece"

has. Universal Electronic Mulineler with 0.025 m /

sec. to max. 12 m / sec. flow rate measurement between

done.

Handle

2 m. Stems in the neck (two

pieces) made of stainless chrome-steel pipe.

Stems are spaced 10 cm apart for easy reading

It is a feature. 0 cm to 20 cm 1 cm. the beakers.

Cable

The number of revolutions seen with the return of the propeller in water

with a contact cable (3 m.)

Transmitted. The plugs on the cable ends are made of stainless chrome material.

Calculation of Flow Rate

The flow rate of the water is obtained according to the number of revolutions to be obtained at the end of the turn of the propellers. Speed ​​achieved

The k and Δ parameters in the formula v = k.n + Δ used are determined when the instrument is calibrated. These parameters

and & quot; n & quot; values ​​indicative of the speeds at the & quot; n & quot; speed are copied to the memory of the electronic numerator device

reported and reported

v = k. n +?

v = Water velocity (m / sec.)

k = hydraulic gradient of the propeller in water (m)

n = a round trip average of the propeller

Δ = According to the values ​​obtained from the tests made on an open calibration channel of the Universal Mulleren

characteristic (m / sec.)

Constant values ​​k and Δ due to mechanical differences in propeller and shaft bed between the Current Meters

channel (DSİ-TAKK).

Calibration values ​​are given in tables with the current meter
