Measure the flow rate of high-temperature liquids. As your liquid flows through these flowmeters, it pushes an indicator up the scale, showing you the flow rate. Mount them vertically inline with your piping system, so liquid flows up from the bottom. They have union fittings, making it easy to position the scale so it’s visible. The fittings are plastic, so they work with a wide range of chemicals.

These flowmeters are calibrated using water but can be used with other liquids. If you’re using these with a liquid other than water, 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.

Check the flow rate of liquids up to 200° F from an easy-to-read digital display instead of a scale or dial. These flowmeters measure flow by counting how many times their turbine turns as liquid flows through. To avoid clogging the turbine and other damage to these flowmeters, use them only with clean, low-viscosity liquids. Mount them inline with your pipe system. Their fittings are polypropylene, which works with a wide range of chemicals. NEMA and IP rated, these flowmeters stand up to dust, weather, corrosion, and water from washdowns.

These flowmeters are calibrated with water but can be used with other liquids. If you’re using these with a liquid other than water, 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.

Install these flowmeters in an instrument panel to measure the flow rate of hot water and other liquids reaching up to 212° F. They should be mounted vertically, so liquid flows up from the bottom. As liquid flows through, it pushes an indicator up the scale, showing you the flow rate.

These flowmeters are calibrated with water but can be used with other liquids. If you’re using these with a liquid other than water, 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.

Flowmeters with a flow-control knob let you open and close the inlet valve to adjust the flow rate within the range.

Send flow rate measurements to monitor and control equipment. Also known as transducers, these transmitters convert flow rate measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). As flow increases, the output signal increases. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Mount them directly inline with your system. They measure flow correctly no matter their mounting orientation.

These transmitters are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.

Turbine transmitters measure flow by counting how many times their turbine turns as liquid passes through. To avoid clogging the turbine and other damage, use them only with clean, low-viscosity liquids. The digital output sends flow data with a pulse, which is a spike of voltage. The higher the flow, the more pulses they send. The voltage of the pulse output matches the input voltage sent to the transmitters. These transmitters meet NSF/ANSI 61 for use with drinking water.

With one meter, these flowmeter/totalizers measure the flow rate and total flow volume of high-temperature liquid up to 200° F. They count how many times their turbine turns as liquid passes through to measure flow. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. The batch total can be reset after each metering application. They come set for batch totalization, but you can disable the reset function to operate as a cumulative totalizer. They measure flow correctly no matter the mounting orientation.

These flowmeter/totalizers are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.

The digital display on these totalizers makes it easy to check the total amount of high-temperature liquid—up to 200° F—passing through your system. They measure flow volume by counting how many times their turbine turns as liquid passes through. To avoid clogging the turbine and other damage to these totalizers, use them only with clean, low-viscosity liquids. The batch total can be reset after each metering application. They come set for batch totalization, but you can disable the reset function to operate as a cumulative totalizer. They measure flow accurately no matter the mounting orientation. Rated NEMA 4X and IP65, they seal out dust and protect against washdowns and corrosion.

These totalizers are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.

The indicator moves when flow is present, so it’s easy to visually confirm flow from a distance.

Sights with a bronze body are harder and more durable than sights with a brass body for a longer service life.

Sights with a 316 stainless steel body are more corrosion resistant than sights with a brass or bronze body.

Rotor indicator is the most obvious indicator of flow for maximum visibility.

Back window can be backlit to increase the visibility of dark liquids.

The included mounting ring lets you install these sights in instrument panels. They have three ball indicators that bounce in the domed-top window to show flow in your line.

Since they come factory set to a specific set point, these switches are easier to install than adjustable flow switches. As flowing liquid pushes an internal piston, the switch reads the position of the piston to measure the flow. When the piston passes the set point, the switch actuates. They’re accurate in any mounting orientation.

These switches are calibrated with and measure water accurately. They can also be used with other liquids by applying your liquid’s specific-gravity conversion factor to calculate the new set point.

Choose a fitting material that is compatible with the liquid you intend to run through your line. Polypropylene and PPS plastic fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

SPST (single pole, single throw) switches turn one device from off to on (normally open).
