Dual Pulse Insertion Flow Meter

The Flomec Dual Pulse insertion flow transducer is an innovative design combining well proven technology with the performance enhanced by the use of modern engineering materials to provide a cost effective and reliable means of measuring the flow of a wide variety of low viscosity of liquids.

A durable peek rotor with a graphite-PTFE impregnated peek bearing rotates around a precission ground tungsten carbide rotor shaft to promote longevity.
The body is all 316 stainless steel. The unique metering head & aerofoil shaped
rotor are shaped to extend the linear measuring range to cover flow velocities from 0.3-10m/sec (1-33ft/sec).

Wide Application
Typical industry applications include:
HVAC - Hot & chilled water, Fire system& Thermal energy monitoring.
Municipal- Water distribution, Water management and Water treatment.
Irrigation- Water management.
Water treatment- Chlorination,De-salination & mechanical filtration plants Chemical injection systems.
Refineries- Primary flow additive injection,Fire & cooling systems.
Power generation- Boiler feed water, Steam condensate, Process water & water balancin
Chemical - Process & cooling tower water,Chemical & water batching.
Others- Cement Mfg, Diesel fuel transferring, Flow testing, Fire truck &
Hydrant flow monitoring, Food processing, Pulp/paper, Mining.
