Service Record In Landfill Applications

Open Flow Path Of Mag Flowmeter Means
That Entrained Solids Are Not A Problem

The Rosemount 8700 series flowmeters are designed to measure the flow of conductive liquids in full pipes.  The sensor and transmitter can be provided as either an integral assembly or as a remote mount configuration.

The design is based on Faraday’s Law which states that the voltage induced in a conductor moving through a magnetic field is proportional to the velocity of that conductor.  In this way, the flowmeter measures the flow velocity of the pumped liquid as it passes through the obstructionless flow tube.  Volumetric flow rate is then calculated based on meter size and  measured velocity.

The flowmeter’s high signal frequency makes it ideal for accurate measurement in applications with high levels of noise induced by entrained solids.  This, coupled with the through flow, solid state construction create a reliable, rugged package for landfill flow measurement.
