Electromagnetic Flowmeter CMM15 ManuFlo Vietnam

 

 

 

INTRODUCTION:


The CMM Mini-Mag is a low-cost compact Electromagnetic Flowmeter, suitable for industrial applications for flowrate and totaliser liquid metering and batching.


Liquids with an electrical conductivity of at least 50µS/cm can be measured. The converter/processor is inbuilt on the flowmeter sensor primary. These two elements form a very compact package.


With no moving parts and an obstruction-free bore, this type of flowmeter is ideal for measuring a wide range of conductive liquids (that are chemically aggressive, or dirty) up to a temperature of 90 °C, with minimal head losses and virtually no ongoing maintenance. CMM Mini-Mag is ideal for measurement of recycle water or water based liquids including admixtures with impurities, providing flowrate or total display for shotcrete and for process batching/monitoring applications. The MiniMag can be used in conjunction with a remote ManuFlo FRT-303 Indicator, ME4-T reset counter, ME-series Batch Controllers, ME2008 batch interface cards, UIC scaler cards or can be connected to 3rd party PLCs via the onboard pulse output.


PRINCIPLE OF OPERATION:


The operation of electromagnetic flow meters is based on Faraday's Law of Induction. A voltage is induced in a conductor as it moves through a magnetic field. This principle is applied in the Mini-Mag design. The voltage induced in the flowing liquid is measured at two electrodes, and is proportional to the average flow velocity. The microprocessor then scales this signal voltage to read in digital units.
