Dwyer Series TUF Ultrasonic Energy Meter

Wiratama Mitra Abadi 01 22.39 flow measurement,

Dwyer Series TUF Ultrasonic Energy Meter is a highly accurate and stable energy meter that utilizes ultrasonic technology to measure heating and cooling energy consumption. The Series TUF is a compact meter with a flowmeter and energy calculator in one, making it great for installation on chillers and boilers.

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators, and Controllers are ideal for the measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston.

Flow Transmitters are sensors with an electrical transmission output for remote indication of flow rate. The different transmitters are Ultrasonic, Paddlewheel: in-line, adjustable and fixed, electromagnetic: adjustable, in-line and fixed, and turbine: in-line. Accessories and Fittings for these flow transmitters are also in this category.

Ultrasonic flow transmitters are sensors with electrical transmission output for remote indication of liquid flow rate. Models are cost-effective, compact, and lightweight. Applications include treated water, river water, diesel oil, data logging, flow measurement for heating metering, and utility billing.
