Flowmeter FAQ’s

What types of pickup coils are available and how is the coil selected?

Flowmeters, Flowmeter Pickup Coils

Generally speaking the pickup coil is selected based on meter size and desired turndown range. Hoffer offers many different types of magnetic pickup coils with different gauss levels.  In addition, Hoffer offers modulated carrier pickup coils which provide turndown ranges of 100:1 in some configurations.
