Dwyer Flow Meter DTFW Series

Dwyer Flow Meter DTFW Series

Online installation of liquid variable area flowmeter with 2% FS accuracy

The DTFW series liquid variable area flowmeter measures water flow at a competitive price, with an accuracy of ± 2% of full scale. The durable metal structure ensures excellent compatibility and strength to withstand system pressures of up to 3000 pounds per square inch (200 bar). Provide 1/4 “, 1/2”, and 1 “connectors, with a choice of high-quality brass or stainless steel structures. Pre calibrated for horizontal online installation.

Application monitoring of filter or filter pressure drop, based on differential pressure flow scale, hydraulic equipment, oil and natural gas equipment, heat exchanger backflow prevention

feature

Durable metal structure ensures extremely high reliability and strength to withstand system pressures of up to 3000 psig (200 bar),

Unlike glass tube variable area flow meters, the shatterproof structure produces a longer service life

Accurately perform preforming in environments with high temperature, high vibration, and susceptibility to impact
