The HM-E AND HMP-E FLOW METER VERY VERSATILE – brought to us by Anderson-Negele

 

Anderson-Negele’s HM-E and HMP-E Flow Meters can be used successfully in applications without conductivity, such as:

  • oil measurement (careful: particles / viscosity)
  • water: reverse osmosis water i.e. in soft drink production, condensate, pharma WFI (water for injection) and others
  • where ever it can replace mass flow

Dairy

  • For water batching
  • For water control (hose applications)
  • Hot water dispensing (the wash down of cream transport)

Beverage

  • Filling machine, as it is fast acting
  • Drum rinsing, as it is compact

Pharma

  • WFI batch stations
  • Filtration monitoring

The Principle of Operation

As shown by the first Anderson-Negele image, we have A and C, upstream and downstream flow straighteners, respectively.  They stabilize the incoming liquid, so that the flow will move through the rotor B linearly.  On contact with B, the liquid then causes the rotor to rotate a shaft which is part of the downstream flow straightener.  As a result, the velocity of the liquid moves through the meter.

We move to the second image, where we see the signal probe (1) which contains components which generate an electromagnetic field (3) made possible by the internal oscillating circuit named 2.  An induction current or eddy current is produced in the turning rotor vanes.  The electromagnetic field, which is generated, counteracts the magnetic field from the oscillating circuit, which causes a change in the oscillating circuit voltage.  Number 4, the integrated amplifier changes into a pulse signal.  Because the frequency created by the vanes corresponds with the rotation of the rotor, the pulses put out equal to the volume of the liquid moving through the meter.

 

 

With proper location, you will get the following from Anderson-Negele’s flow meters:

  • Positive pressure operation
  • Full liquid fill at measuring point
  • No signal noise
  • Extremely robust flow meter
  • No electronics that could be damaged
  • Very compact flow meter
  • No conductivity needed (i.e. demineralized water)
  • Very fast response
  • Easy to inspect, maintain, and repair
  • 3A approval, and hygienic design
  • Low cost alternative to magnetic flowmeters
