Electromagnetic flow meters | Sure Instrument

Electromagnetic flow meters are intended for fluid measurement in most industries including water, wastewater, food and beverage, pharmaceutical and chemical.

There are two basic components of electromagnetic flow meter: 1) The Detector, which includes the flow tube, isolating liner and measuring electrodes, and 2) The Converter, which is the electronic device responsible for signal processing, flow calculation, display and output signals.

The materials of construction of the wetted parts (liner and electrodes) should be appropriate for the specifications on the intended type of service. Review of the compatibilities consistent with the specifications is recommended.

Our electromagnetic flow meters are factory tested and calibrated. A calibration certificate is included in the shipment of each meter.

DESCRIPTION

The magnetic flow meter is one of the most flexible and universally applicable flow measurement systems available.
It is a volumetric flow meter which does not have any moving parts and is ideal for waste water applications or any dirty liquid which is conductive or water based.
Magnetic flow meter is also ideal for the applications where low pressuredrop and low maintenance are required.

OPERATING PRINCIPLE
Following Faraday’s law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field.
In the electromagnetic measuring principle, the following medium is the moving conductor The voltage induced is proportional to the flow velocity and is upplied to the amplifier by means of two measuring electrodes.
The flow volume is calculated by means of the pipe cross section area.

APPLICATION
Waster water industry: transport networks sewage treatment plants, sludges
Chemical industry: acids alkalis, dosing applications, abrasive or corrosive mediums
-Metal & mining industry: mediums with a high solid content, like ore or excavator mud
Water industry: Revenue metering, district metering waterabstraction, leakage detection
Pulp & paper industry: pulp, pastes, sludges & other caustic mediums, liquor, additives, bleaches, colourants
Food & beverage industry: mixing, dosing and filling of drinks under hygienic conditions filling systems applications
