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.

A ball indicator increases the visibility of flow for checking at a distance.

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.

About half the height of other flow sights for chemicals, these fit in areas with limited clearance.

Measure the flow rate of water in your system.

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

Often used in laboratory applications, these flowmeters have a scale in liters or milliliters.

The transparent body lets you inspect water color and clarity in addition to measuring the flow rate.

For easier reading from a distance, these flowmeters have a prominent dial instead of a scale. They can withstand pressures up to 3,000 psi.

Rated for pressures up to 3,500 psi.

The PVC body can withstand corrosive chlorinated and deionized water.

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

Rated for nearly double the temperature of standard panel-mount flowmeters for water, these can withstand up to 212° F.

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

For installation in instrument panels, these flowmeters have fittings on the back.

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

Measure the flow rate of compressed air.

Measure the flow rate of hydraulic and motor oil.

The correlated scale and conversion charts let you use the same flowmeter for nitrogen, oxygen, argon, and helium.

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

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

With a display that can be placed up to 25 feet from the sensor, these flowmeter/totalizers are often used in hard-to-access areas.

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

Measure the total flow volume of water in your system.

Withstand temperatures of at least 194° F.

These totalizers meet NSF/ANSI Standard 61 for use in drinking water systems.

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

Often used in heating, cooking, and power-generating systems.

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

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

The metal body can withstand oil.

These switches have a low-profile design to fit in water pipelines with limited clearance.

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

For installation in environments with flammable gases and combustible dust, these flow switches are UL listed for use in hazardous locations.

Combine a pair of valves with a gauge glass and four guard rods to build a complete level indicator.

These flexible indicators bend to follow the contours of a tank.

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

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 probe on a cord, these meters access hard-to-reach places in duct.

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.

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