Measure the flow rate of water in your system.

Instead of a scale, these flowmeters have a prominent dial that’s easy to see from a distance. Dial displays readings in gallons.

For faster installation and disconnection than standard flowmeters for water, these flowmeters have union nuts on both ends.

Rated for pressures up to 3,500 psi.

Union nuts on both ends make it easy to install and remove these flowmeters from your system.

A 304 stainless steel case protects these flowmeters from blows that could shatter the glass body.

Fittings on the back let you install these flowmeters in instrument panels.

A rugged, impact-resistant case protects these flowmeters from damage.

Install these flowmeters without disassembling your pipeline. Drill a hole in an existing run of PVC pipe and secure the flowmeter with the included clamps.

The prominent dial is easier to read from a distance than a standard scale.

With a prominent dial instead of a scale, these flowmeters are easier to read from a distance than other high-pressure flowmeters for air.

For protection against damage, these flowmeters have a rugged, impact-resistant case.

Designed for more than 10 times the pressure of standard flowmeters for oil, these are rated for pressures up to 3,500 psi.

With double the temperature rating of standard flowmeters for oil, these can be used with oil up to 400° F.

Directly install these flowmeters in your pipeline. They can be used with water containing particles up to 1/8” in diameter.

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

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present.

A large tubular window provides an unobstructed view of liquid color, clarity, and movement from multiple angles.

Withstand twice the temperature of standard sights. These are rated for temperatures up to 400° F.

To maintain a clear view of your process media without disrupting flow, twist the tubular window to clear debris and buildup with the internal wipers.

The included mounting ring lets you install these sights in instrument panels.

Built to withstand harsh chemicals.

Bond the unthreaded connections to PVC pipe with PVC cement and primer.

Determine the flow rate and total flow volume of water with the same meter.

For secure connections in large pipelines with high flow rates, these flowmeter/totalizers have flanged ends.

Designed for use with light oils.

Three times more accurate than standard totalizers for water, these are rated for ±1.5% accuracy.

The enclosure meets NEMA 4X to protect these totalizers from dust, washdowns, and corrosive liquids.

With a display that can be mounted up to 1,000 feet from the body, these totalizers are often installed in hard-to-access areas and remote locations.

More than twice as accurate as standard totalizers for fuel, these are rated for ±2% accuracy.

Install this totalizer on your grease gun to accurately measure grease dispensing and reduce waste.

Calibrated for compressed air.

For precise measurement of water, hydraulic fluid, or diesel fuel level, this gauge provides level readings down to 1/8".

Install these gauges through the top of your tank to monitor diesel, fuel oil, or gasoline level.

With a stainless steel float and float rod, these gauges resist corroding from chemicals.

The nylon body and window make these indicators shatter resistant.

Check both the temperature and the hydraulic fluid or oil level in a pressurized system.

Made with clear, shatter-resistant plastic, these indicators don't require a shield to protect them like other oil-level indicators, so you can check your hydraulic fluid or oil level from any angle.

The nylon body and window make these indicators shatter resistant.

Bend these flexible indicators around the contours of your hydraulic fluid, oil, or water tank. Because their plastic resists shattering, they don’t need a protective shield like other liquid-level indicators, so you can check your tank’s level from any angle.

Replace existing gauge glass or combine with valves and guard rods to build your own level indicator.

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

With a thick glass window fused to a metal body, these sights resist cracking at high pressures.

Machined from one piece of stain- and impact-resistant plastic.

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

Often used in kilns and other heating equipment, these sights have a quartz window that can withstand temperatures up to 1600° F. They're also known as peep sights.

Weld these sights to single-wall tanks.

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside.

Add a window to your high-vacuum system. With a pane of glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds.

The metal body can withstand oil.

These switches have a fixed set point for applications with consistent flow.

An adjustment screw lets you alter the set point to suit your application.

For flow monitoring at a glance, these switches have a plastic window with a rotor that spins when flow is present.

For use in cooling and process systems.

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Refill U-tube gauges.

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

Use in high-pressure applications up to 3,000 psi.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

This meter is often used to test airflow through supply and return grilles and air filters.

Often used to detect clogged air filters and iced air conditioner coils, these switches sense small changes in pressure between two points in your duct.
