The OPTIFLUX electromagnetic flowmeters
, UFM 3030 ultrasonic flowmeters, and OPTIMASS Coriolis Mass flowmeters are used extensively to accurately monitor and measure the flow of liquids and gases through pipelines.
Products on display will include ABB's AquaMaster electromagnetic flowmeter
featuring a revised transmitter design and built-in GSM technology, enabling remote access to flow data using SMS messaging.
ABB LIMITED'S new electromagnetic flowmeter
, the FSM4000, is designed to provide greater stability for chemical/additive dosing applications.
Ultrasonic doppler flowmeters, laser doppler flowmeters, and electromagnetic flowmeters
are the main products available in this market.
are well-suited to the demands of wastewater flow measurement applications.
Flow-sensing systems, typically electromagnetic flowmeters
, are used with liquid applicators, including tankers and towed-hose or umbilical-cord units.
