High-Temperature and Pressure Flowmeters for Oil

If the oil in your line is too hot or pressurized for standard flowmeters, use these flowmeters to measure the flow rate. As oil flows through, it pushes an indicator up the scale, showing you the flow rate. The scale rotates 360°, so you can check the flow rate from any angle. These flowmeters measure flow correctly in any mounting orientation. Install them inline with your pipe system.

These flowmeters are calibrated with oil but can be used with other liquids. If you’re using these with a liquid other than oil, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.

Choose a fitting material that is compatible with the oil you're running through your line.

Compact Flow Sights with Indicator for Water and Oil

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present. They have a low-profile body for installation in pipelines with limited clearance. Backlight the back window to increase the visibility of dark liquids.

303 Stainless Steel Body—Sights with a 303 stainless steel body are more corrosion resistant than sights with a brass or zinc-plated steel body.
