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.

Insertion Flowmeters
No need to disassemble your PVC pipeline—insert these flowmeters into a drilled hole and secure them using the included clamps. As liquid flows through the meter, it pushes an indicator up the scale, showing you the flow rate. They have a clear body, so you can check the color and clarity of flowing liquid to identify and diagnose problems. Mount these flowmeters vertically.
These flowmeters are calibrated with water but can be used with other liquids. If you’re using these with a liquid other than water, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.

Noncontact Flow Transmitters
Using ultrasonic waves, these transmitters measure the flow rate of your liquid from outside your pipe. They're a good choice for applications where you need to retrofit your system or avoid liquid coming into contact with the transmitter. Also known as transducers, these transmitters convert measurements to an electrical pulse that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). The pulse outputs match the input voltage of the transmitter. The higher the flow, the more pulses they send. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Configure them for either a 4-20mA or digital pulse output when installing.
A digital display makes it easy to check flow rate and configure settings. Clamp these transmitters onto your pipe with the included mounting hardware and gel pads. They measure flow no matter the mounting orientation.
These transmitters are calibrated with water but can be used with other liquids and will generally measure accurately, even if they differ in viscosity and density. You can recalibrate them in the field for accurate readings on pipe and operating conditions.
