About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Threaded Plug Gauges with Handle for Pipe Threads
Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly. All are precisely manufactured to tight thread tolerances. If the gauges wear down, you can install new ones (not included) on the taperlock handle.
Use gauges with NPSM and BSPP threads for go/no-go tests. The end with a go gauge checks the minimum internal thread size, and the end with a no-go gauge checks the maximum. Your fitting is within tolerance if it’s easy to thread in the go gauge but difficult to thread the no-go gauge more than two turns.

Threaded Ring Gauges for Pipe Threads
Confirm that external pipe threads are sized within tolerance. Manufactured with precision, these gauges meet tight thread tolerances themselves.
Use gauges with NPSM and BSPP threads in pairs for go/no-go tests. Go gauges check the maximum external thread size, and no-go gauges check the minimum. If the threads you’re testing thread into the go gauge but not the no-go gauge, they’re within tolerance.

Socket-Connect Flowmeter/Totalizers with Remote Display
Often used in hard-to-access areas, these flowmeter/totalizers have a display that can be placed up to 25 feet from the sensor. Use them to measure the rate and volume of liquid flowing through your system. They measure flow by counting how many times their turbine turns as liquid flows through. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. Batch totals are resettable but can be protected with a security code to prevent tampering. The reset function can also be disabled so that they operate as a cumulative totalizer. Cumulative totals cannot be reset. No matter the mounting orientation, they’ll measure flow correctly.
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.
For a complete unit, you’ll need a display, a sensor, and a tee fitting (all sold separately).
Sensors thread onto the tee fitting (sold separately).
Tee fittings mount inline with your pipe. They have two unthreaded socket ends that bond to unthreaded PVC pipe with PVC cement and primer.

Humidity-Indicating Plugs
Monitor humidity in sealed containers without opening them, protecting the inside from contamination. These plugs are often used on plastic bags, storage containers, and electrical housings. Consisting of a mounting nut and two gaskets for a tight seal, these plugs install through a hole in a flexible barrier. Remove one gasket and reverse the nut to install plugs in a rigid container. Watch the indicator disc through the nut’s viewing window—it will change color as humidity rises and falls. Made of anodized aluminum, these plugs resist corrosion and are lightweight. They meet military and SAE standards for humidity indicators.
