Electromagnetic Flowmeter – Inline Previous ProductNext Product

World’s First Flow-Liquid System

Electromagnetic flow measurement has been in use around the world for 50 years and more, as witnessed by the popularity of these meters that continues unabated in virtually all sectors of industry. Electromagnetic Flowmeters can be used to measure all electrically conductive liquids (> 5 µS/cm) with or without solids, e.g. water, wastewater, sludge, slurries, pastes, acids, alkalis, juices, fruit pulp, etc. It is based on Faraday’s law of Electromagnetic Induction. The meter features flanged construction and is available with choice of liner and electrode material. All meters consist of a sensor and a converter that may be mounted either integral to the sensor or remotely with a field mount kit. Flowmeters are calibrated at our own Water Flow Calibration Facility. It uses the primary method of measuring the water flow by gravimetric principle. The facility is designed for calibration of flowmeters under controlled and stable flow conditions.

Overview

Electromagnetic Flowmeters are based on Faraday's Law of Electromagnetic Induction.

In an Electromagnetic Flowmeter, the magnetic field is generated by a set of coils. As the conductive liquid passes through the electromagnetic field, an electric voltage is induced in the liquid, which is directly proportional to its velocity. This induced voltage is perpendicular to both the liquid flow direction and the electromagnetic field direction. The voltage sensed by the electrodes is further processed by the transmitter to give standardised output signal or displayed in appropriate engineering unit. The flux density of the electromagnetic field in a given Flowmeter and the distance between the electrodes are constant. Therefore, the induced voltage is only a function of liquid velocity.

Features

Based on Faraday’s law of electromagnetic induction, these flowmeters are suitable for virtually all types of conductive liquids (> 5 µS/cm) with or without solids, e.g. water, wastewater, sludge, slurries, pastes, acids, alkalis, juices, fruit pulp, 

The measuring tube is available in SS 304 and SS 316L with PTFE and Rubber lining

An economic version in Plastic Body, is an ideal cost and energy efficient flowmeter and is rust free.

The Flow tube sizes range from 10 mm to 3000 mm and above.

The Coil assembly is structured in hermetically sealed welded construction. This makes the electronics field changeable.

The flow meters come equipped with remote type and integral type transmitter.

An absolute zero stability and noise elimination due pulsed DC excitation offers high long-term stability and reliability

Easy installation and absolutely low maintenance, No pressure loss offer excellent accuracy and repeatability.
