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 Flow and Temperature Transmitters
Thread a ring fitting (sold separately) into your pipe connection and insert the probe of these transmitters to measure the flow and temperature of water, oil, or air. The probe is held in place with a compression fitting on the other end of the ring fitting. They’re often used in large-diameter pipes where it would be difficult to install a transmitter inline. To calculate the flow rate, these transmitters generate a small amount of heat, then measure the cooling effect your liquid or air has on it. They measure and output both flow and temperature, making them ideal for applications where temperature fluctuates. Also known as transducers, they convert measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs) to monitor flow or control equipment. As flow or temperature increases, the output signal increases. 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. They’ll measure flow correctly in any mounting orientation. These transmitters are calibrated with air, glycol solutions, oil, and water but can be recalibrated in the field for other liquids.
Adjust settings at the source using the digital display. These transmitters have two configurable outputs. One can be wired for flow or temperature as an analog output or a digital switch. The other one can be wired for flow as a digital switch, digital pulse output, or IO Link. Pulse outputs send flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send. To change settings and receive error messages remotely from your PLC or computer, you can program one of the outputs to use IO Link. You’ll need an IO Link controller (not included) to connect to your interface.

Contact/Noncontact Tachometers
Capture high-speed readings from a distance in noncontact mode or use the speed wheel to switch to contact mode. This tachometer comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. It has a 1/4"-20 female threaded bushing for tripod mounting.
BNC cable (sold separately) sends signals from the tachometer to a data collector.
