Product Q&A

Q:What is a battery powered electromagnetic flow meter for chemical dosing?

It is a flow meter designed for measuring and controlling precise chemical injections in water treatment and industrial processes. It runs on internal batteries, eliminating external power needs

Q:What is the accuracy?

The meter provides pluse-minus 0.5% accuracy, ensuring precise measurement of costly chemicals and accurate dosing rates.

Q:Why use a mag meter for chemical dosing?

Mag meters offer high accuracy, no moving parts (minimizing maintenance and failure risk), and are available with corrosion-resistant materials to handle aggressive chemicals.

Q:What chemicals can it handle?

The meter can handle a wide range of chemicals, including acids, alkalis, coagulants, flocculants, polymers, and oxidizing agents. Material selection depends on the specific chemical.

Q:What are typical applications?

Water and wastewater treatment, pH control, chemical injection skids, polymer dosing, and industrial process chemical feed.
