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.

Avoid complicated inline installation—these flow switches insert into a tee or pipe outlet, so you don’t need to disassemble your pipeline. They have a paddle that’s pushed as your liquid moves through to determine flow. When the paddle reaches a set position determined by the set point, it activates or deactivates equipment. They are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). They should be mounted vertically into a large-diameter horizontal pipeline, so liquid pushes the paddle.
These flow switches 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.
Switches with a Noryl plastic body have a paddle that you trim to adjust the set point. The more you trim, the higher the set point.
Choose a fitting material that is compatible with the liquid you're running through your line. Noryl plastic fittings work with a wide range of chemicals. Brass and 316 stainless steel fittings resist impact better than Noryl plastic fittings.
Socket-connect flow switches bond to an unthreaded PVC pipe tee or pipe outlet with PVC cement and primer (not included).
IP65 rated switches seal out dust and can be lightly rinsed.

Flow Transmitters for Flanged Pipe
Install these transmitters between two flanges in a flanged pipe system to measure flow rate and send the data to a remote display or programmable logic controller (PLC). For easy cleaning and maintenance, you can slide the transmitter out from between the flanges. A complete transmitter consists of a flow transmitter, display, and mounting hardware kit (all components sold separately). Flowing liquid turns the turbine in the transmitter, while the easy-to-read display counts the number of turns to measure and transmit the flow. The display also shows total and batch flow volumes. Use these transmitters with clean, low-viscosity liquids to avoid clogging or other damage to the internal parts. Mount them inline with your pipe system. They’re accurate in any mounting orientation.
Also known as transducers, these transmitters help you monitor status or control equipment by converting measurements to a digital pulse that can be interpreted by receiving devices. Each pulse is a spike of voltage. The higher the flow, the more pulses they send. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the measurement range and output signal of the transmitter. Transmitters will only provide accurate readings within the rated measurement range.
The transmitters are calibrated with water but can be used with other liquids.
