Sparling Magnetic Flow Meters are based on Faraday’s Law of Magnetic Induction. In a magnetic flow meter, the liquid acts as a conductor as it flows through the pipe. This induces a voltage which is proportional to the average flow velocity – the faster the flow rate, the higher the voltage.
This voltage is picked up by sensing electrodes mounted in the meter tube and sent to the transmitter which takes the voltage and calculates the flow rate based on the cross sectional area of the meter tube.
Fields of Application
- High percentage of solids – Sludges, slurries, minerals, paper, sewage – flows with high levels of solids which cannot be measured other types of meters.
- Obstruction less measurement – Nothing projects into the flow stream, no head loss, no parts to maintain.
- Very corrosive liquids – Acids, caustics and corrosive chemical additives are isolated from the meter by inert linings and electrodes.
- Conductive Liquids – Liquids where conductivity is at sufficient levels to induce measurable voltage.
