Dwyer Series DTFW Dial Variable-Area Flow Meter for Liquids

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flowmeters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flowmeters have a variety of applications.

Dwyer offers different types of Dial Flowmeters for various applications. Flow meters measure water, oil, gas or air flow rates. Applications include calculating required fill or drain times for tanks, water towers, backflow prvention, heat exchangers, and oil & gas equipment.

The Series DTFW Dial Variable-Area Flow Meter for Liquids measures water flow rates with ± 2% of full-scale accuracy at a competitive price. Durable metal construction ensures great compatibility and the strength to withstand system pressures of up to 3000 psig (200 bar). 1/4", 1/2" and 1" connections are available, with construction choices of a high quality brass or stainless steel. Comes pre-calibrated for horizontal in-line mounting.

Features

• Durable metal construction ensures great reliability and the strength to withstand system pressures of up to 3000 psig (200 bar)
• Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life
• Preform precisely in high temperature, high vibration, shock-prone environments

Application

• Monitoring pressure drop across filters or strainers
• Flow scale based on differential pressure
• Liquid level given pressure differential between bottom and top of tank
• Hydraulic equipment
• Oil & gas equipment
• Heat exchangers
• Backflow prevention
