Pulsing Flow Measurement

Pulsing Flow Measurement

Pulsing Flow Measurement

(OP)
I am trying to find an instrument that would be able to measure a flow of peroxide through a metering pump. The range is very low( 2 - 8 litres/Hr). I haven't decided if we need to have the signal transmitted or if a local indication would do. I am hoping to find something that would verify that the metering pump is in fact accurate. With such a low flow and the fact that it is pulsing, I think a magmeter would not satisfy our requirements.
Thanks...Tim

RE: Pulsing Flow Measurement

Can you use something like a suction draw-down meter tube?  They are a calibrated tube where you have a valve between them and the tank.  You close the tank valve so the pump draws down the fluid in the tube.  It's typically scaled so that it's easy to read off your injection rate.

I've seen these used on pipeline and other chemical metering pumps.  Is the peroxide such that something like this isn't acceptable from a safety or other point of view?

RE: Pulsing Flow Measurement

Try a positive displacement meter.

A "Trimec Multipulse" will handle pulsing ok over a range of viscosities & impurity levels.

Thermal loss flow sensors may also work (on average) (Namco & others)
