The FPD3200 Series positive displacement flowmeters are affordable and accurate. One primary feature is the ability to maintain consistent accuracy despite changing viscosity conditions. The meter’s solid construction and excellent dynamic response are well suited to measurement for many industrial as well as other non-abrasive lubricating fluids. Since there is no need for straight run piping upstream or downstream of the flowmeter, the FPD3200 flowmeters are simple to use and to install. The meter has good resolution and high accuracy at low flow rates.

How to connect the FPD3205 to the DP3300-TC-4? which wires from meter go to display inputs? Pulse input?

Asked by: rbuck
Thank you for you inquiry on the flow meter. Best to use the Hall Effect wiring diagram indicated in the manual. The 3 wires, red (+), white (signal), and black (-)

I was told that the FPD3205 wont work with DP3300-TC-4? planning on buying replacement display DPF75 so the flowmeter has power. is this the best choice with using FPD3205? I strictly need to display flow rate. (GPM)

Asked by: rbuck
Thank you for your inquiry about the flow meter. If you need to display for flow rate only, then, the DPF78 is a rate meter that will provide power to the flow meter.

Is this positive displacement flow meter suitable for measuring ~1Hz pulsatile flow or would a different product be preferred for that kind of application?

Asked by: CBR4
Thank you for your question? FMG81A mag meter works best for pulsating flow. This is the only flow meter that states on the spec sheet, all others, require constant flow.... hope this was helpful?
