Impeller flowmeters

Meister

Paddlewheel and impeller flowmeters have oscillating plates that allow fluid measurement. The rotating element generates a pulse when it passes a magnetic or optical sensor. The number of pulses is proportional to the velocity of the fluid at a given point in the pipe or duct. They offer relatively high accuracy at a low cost. Some insert versions are very easy to install. Our quote will always be lower than the manufacturer's price. Please send us the full part number of a device to get a quick response.

Flowmeter SPKM

Flowmeter
SPKM

Flow switch SPKM for liquids vane type with an electric microswitch controlled by a moving magnet. The instrument is factory calibrated for horizontal flow. SPKM flow monitors operate on the principle of the paddle flow monitors. It is designed for installation in pipe systems. The spring-loaded paddle inside the device is moved by the medium flowing through it. A microswitch is actuated by means of a magnet. External measuring devices can be connected at the socket. However, the unit has a spring-loaded paddle that allows it to be mounted in any spatial position, including vertical. In this case, on-site calibration may be necessary to compensate for the weight of the paddle.

  • for fluids (4 - 93 l/min)
  • low sensivity to dirt
  • high switch rating
  • low pressure drop
  • micro switch
Operating pressure, max. 25 bar
Pressure drop 0,01 bar
Temperature, max. 110 °C
Measuring accuracy ±15 % of full scale
Hysteresis Depending on switch value, at least 0,7 l/min

Flowmeter SPKR

Flowmeter
SPKR

Flow switch for liquids vane type with an electric reed switch controlled by a moving magnet. The instrument is factory calibrated for horizontal flow. However, the unit has a spring-loaded vane that allows it to be mounted in any spatial position, including vertical. In this case, on-site calibration may be necessary to compensate for the weight of the paddle. SPKR flow monitors operate on the principle of the paddle flow monitors. It is designed for installation in pipe systems. The spring-loaded paddle inside the device is moved by the medium flowing through it. A Reed-contact is actuated by means of a magnet. External measuring devices can be connected at the socket.

  • for fluids (3,5 - 69 l/min)
  • low sensitivity to dirt
  • high switch rating
  • low pressure drop
  • reed contact
Operating pressure, max. 25 bar
