The Dualpulse 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.

Robust Construction
A durable peek rotor with a graphite-PTFE impregnated peek bearing rotates around a precision 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 0.3-10 m/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 balancing. 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. DATA SHEET No. SLDP000-0601.
