AirMon Flowmeter


AirMon Flowmeter - An innovative cost-effective flowmeter for monitoring of compressed air

Consumption of Compressed Air in the consumption side remains one of the least monitored areas in any network. Identifying the volume of compressed air consumed by any given section of a plant would amount to guesswork by most utility managers.

 

Most solutions for monitoring compressed air consumption on user points are either expensive or inaccurate, or worse, cause energy losses themselves. The Forbes Marshall AirMon is a cost effective alternative to compressed air consumption metering.

 

The AirMon compressed air meter is a highly accurate meter that operates on the Vortex flow metering principle. It’s accuracy of ±2% make it one of the most effective compressed air flow meters in its class. What makes the AirMon unique is that no other flow meter in its class possesses the vital feature of inbuilt Pressure and Temperature Compensation.

1. Working Principle - based on the development of a Karman vortex-shedding street in the wake of a body built into the pipeline.

The periodic shedding of eddies occurs first from one side and then from the other side of a bluff body (vortex-shedding body) installed perpendicular to the pipe axis. Vortex shedding generates a so-called "Karman vortex street" with alternating pressure conditions whose frequency is proportional to the flow velocity.
With an orifice plate, the fluid flow is measured through the difference in pressure from the upstream side to the downstream side of a partially obstructed pipe. The plate obstructing the flow offers a precisely measured obstruction that narrows the pipe and forces the flowing fluid to constrict
2. Accuracy: ±2% of measured value Accuracy: ±3% of measured value
3. Pressure & Temperature Compensation: Inbuilt and Online compensation Pressure & Temperature Compensation: Pressure compensation not available. Additional pressure & temperature transmitters and flow computer required, further reducing accuracy
4. Pressure Drop: Very negligible. Usually < 0.05 bar. Hence reduced energy consumption Pressure & Temperature Compensation: Pressure compensation not available. Additional pressure & temperature transmitters and flow computer required, further reducing accuracy
5. Reliability: Resistant to damage, wear and tear. No erosion of precision of readings Reliability: Any wear and tear causes drop in accuracy of readings.
6. Sensor located behind bluff body – safe from dirt and particulate matter carried in air Susceptible to damage from dirt and particulate matter from wear and tear
