High Pressure Flow Transmitters
Orange Research flow transmitters handle working pressures to 5,000 psi. Machined from solid blocks of metal, the flow transmitter pressure bodies protect sensitive, repeatable sensors within a rugged, protective housing. A magnetic sensor relays slight changes in pressure to the electronics, which amplify and linearize the signal. Changes in flow conditions can be monitored remotely. A comprehensive understanding of flow transmitter types and their benefits empowers you to optimize your systems and maximize performance. Learn more from our experts below.
Flow Transmitter Voltage or Current Output
One flow transmitter unit can be wired for either voltage or current output. Two wire for loop power (4-20mA) use offers more flexibility…there is no need to bring a separate power line to the unit. Installation time and costs are reduced. For voltage outputs (0-5 volt) 3 or 4-wire use is required.
Add Local Indication
These flow transmitters can be configured with or without dials. Many times an easy-to-read gauge is a separate instrument to be specified. Our flow transmitter types have a gauge option which allows for local and remote monitoring! Up to 4.5 inch dials are available, which can be read from over 75 feet away.
Advantages Over Rotameters
- High line pressures (to 5,000 psi)
- Mount in any orientation, not just vertical
- Easy to read dial option – especially with dirty or opaque fluids
Built for industrial applications, our flow transmitters feature a weatherproof enclosure that protects the electronics with Class 1, Div 2, Nema 4X & IP 65 ratings.
Flow Transmitter Applications:
- Coolers & Chillers
- Flow
- Heat Exchangers
- Anywhere Pressure Drop is an Issue
| Power | Outputs | Wiring | Operating Temperature |
|---|---|---|---|
| 9-35 VDC | 0-5 VDC, 4-20 m-A | 2 wire (loop powered current output), 3 or 4 wire (voltage output) | -20° F to 200° F (ambient) Temperature compensated output |
*Instruments that accept two reed switches can be supplied with one SPST and one SPDT switch if desired. Refer to our individual model Specification Sheets for complete specifications listings.

Flow Transmitters
Our instrument sensors include a magnet that moves with the sensor as the pressure or flow conditions change. Our transmitters incorporate a Hall effect sensor that transforms that movement into an electrical output. As the conditions change and the sensor moves into proximity to the Hall effect sensor there is a change in output from the Hall effect sensor that is proportionate to the flow rate.
Every flow transmitter is capable of providing a current and voltage output. The user simply selects the output they require. Temperature compensation ensures that the output of the transmitter does not drift.
Each flow transmitter can be installed as a two-wire current (loop powered) or as a three- or four-wire voltage connection. The safety ratings of the switch enclosures also apply to the transmitters.
