  • ±1% of full scale flow accuracy
  • ±0.2% repeatability
  • Pressures up to 6000 psi (414 bar)
  • Temperatures up to 300°F (150°C)
  • Optional IFC converter provides analog output

The Flo-tech classic turbine flow sensors measure the flow rate of hydraulic fluids and other compatible liquids. Offered in a choice of high strength anodized aluminum or Stressproof® steel bodies, these durable flow sensors are capable of withstanding pressures up to 6000 psi (414 bar).

The Classic series has standard magnetic pick-up, providing a frequency signal that is proportional to the flow rate and can be transmitted to Flo-tech's F6600/F6650 series digital displays. If an analog output is preferred, these sensors are also available with the IFC (Intelligent Frequency Converter) which offers either a 4 to 20mA or 0 to 5VDC output signal. This allows for easy integration with Flo-tech's F6700/F6750 series digital displays, PCs, PLCs, or other data acquisition devices.

Application Notes

Here's how some of our customers used this product.

Skydrol Dispensing Skid

The Background: Our customer is an engineering company that is designing a skid to be used for dispensing Skydrol, an aviation specific hydraulic fluid. They seek a simple mechanical flow sensor to measure the amount of Skydrol dispensed.

The Problem: Skydrol requires specialized equipment for metering. Meters must be calibrated specifically for Skydrol’s viscosity and the meter must have EPR seals as other seals are not compatible with the fluid.

The Solution: We recommended the Flo-tech classic turbine flow sensor which is designed specifically for hydraulic fluids. The Flo-tech Classic turbine is factory calibrated for the correct fluid density and viscosity so no additional customer field calibration is required. The factory was also able to accommodate a special request for EPR seals despite them not being offered as an option for this meter. Paired with a Flo-tech F6600 series display, this flow system is an out-of-the-box solution for anyone looking to measure hydraulic oils.
