Often used in cooling, lubrication, and process systems.

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

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

Rated for more than double the pressure of standard flow sights, these can withstand pressures up to 400 psi.

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.

Made of FDA-listed materials, these sights can be used with food and beverage. They have sanitary quick-clamp connections for easy disassembly and cleaning.

Send flow rate data using these transmitters while also being able to visually confirm liquid is flowing.

Send flow rate and temperature measurements simultaneously to a programmable logic controller (PLC), data logger, or other receiving device.

Thread a ring fitting into your pipe connection and insert the probe of these transmitters to measure the flow and temperature of water, oil, or air.

The nylon body and window make these indicators shatter resistant.

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.

Check the level of liquids containing chemicals such as alcohol-based solvents, boric acid, and sodium bicarbonate.

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

Use this gauge glass with heavy duty level indicators.

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

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.
