JPI EDM 700 Fuel Flow Transducer 231 (Gravity)

Add to Wishlist
Part# 10-27094
MFR Model# 700900-2


The Fuel Flow Transducer measures flows of hydrocarbon fuels such as gasoline, kerosene, and #2 diesel fuel and other light transmitting, non-corrosive liquids of similar viscosity. Typical fuel flow applications include aircraft fuel monitoring systems; gasoline, diesel, and gas turbine engine test stands; and industrial furnaces.

The transducers give repeatable signals on gasoline across a 100 to 1 flow range down to 0.3 GPH. The higher viscosity of diesel fuel reduces signal repeatability at flow rates below 2 GPH. Pressure drops are very low compared to other turbine flow transducers. The transducer bearing system is rated for continuous operation at the upper end of the flow range.

The transducers produce a current pulse signal from an opto-electronic pickup with a preamplifier.

Electrical Specifications:
12 to 15 VDC between RED (+) wire and BLACK (-) wire. 30 to 50 mA at 12 VDC.

Signal Specifications:
Open collector transistor output on WHITE wire. Sensor will pull-down to 1.0 volt with 10-15k ohm pull-up resistor installed.

Good technology, admittedly it is a replacement after 5 years of service. My conversations with JPI have been informative and supportive over the years. I’d recommend the EDM 700.

Q: Does this transducer come with the required fire sleeve?

Yes, a fire sleeve is included with the JPI EDM 700 (10-27094).

Q: Is this unit compatible with the FS450 unit from JPI?

The JPI EDM 700 (10-27094) is compatible with the FS 450 (10-00134) however do not connect the red wire from the FS 450 to the EDM 700.

Q: Is this compatible with the JPI EDM730?

Yes, this is compatible with the EDM 730.

Q: Would this be compatible with marine floscan 5500 which used a floscan 231 fuel flow sensor?

We do not have any data showing this will work in marine applications.

Q: Does this part work with fuel injected engines, or is there a different part number for the JPI 201B?

No, for fuel injected engines, use Part# 10-27089.

Q: By buying this part # 10-27094, do I have to purchase as well the Harness part # 10-04650 or is it included?

You will also have to purchase the harness.

Q: Where is the k factor marked on the transducer? Is there a standard k factor number for these units?

K factor is on the transducer in permanent marker. The pilots guide explains how to adjust. Injected starts 29.00 and gravity 19.00.

Q: Will this work with a Hoskins fuel flow system?

No, This will not work with a Hoskins unit.
