- How It Works
A scaled dial and mechanical indicator continuously monitor the flow rate at any given time whilst electrical switches can be specified to signal when a particular level has been reached during increasing or decreasing flow rates. Minimum Scale 0-4 LPM, Maximum Scale 0-70 LPM (pipe size 1/4’ – 1’)
Style; Through its unique modular design it allows for easy field installation and service. It does not require any straight pipe runs before or after the monitor thus minimizing the installation footprint. The versatile design of the vane monitor allows for orientation to be mounted in any position. Vane style monitor operates when flow is introduced through the inlet connection making direct contact with the vane that is mechanically linked to the indicator shaft. The fluid forces the vane to move through a contoured opening creating a variable orifice, the greater the flow the larger the orifice becomes for flow to pass. The vane style monitor is spring loaded and allows the vane to return on decreasing flows.
Sizes; All sizes are manufactured to the same simple design concept, the main characteristic of which ensures that the pressure drops are confined to an absolute minimum (see “pressure drop” charts) across the vane orifice at full flow, with viscosities as high as 600cS. Sizes are defined by pipe size and/or maximum flow capacity, and every flow switch is individually calibrated so that full scale deflection is used in each application i.e. the maximum scale reading coincides with the maximum requirements of system as specified by the customer. Calibration may be in any units with Single or Dual scale to specification

what is the solution if the pointer stick in a position?
Answer: In the event of a pointer appearing to stick in one position, remove centre housing and clean away pipe scale to ensure that valve plate is free to return to its seating position. (A spacer can be provided so that the flow can pass through whilst maintenance is being carried out)
If the pointer ‘trembles’ allow flow to continue
Answer: ‘Trembling’ is usually air entrapment, and this will be eliminated when the system becomes full.
