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.

Refrigeration Pressure and Vacuum Gauges
Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement. Also known as compound gauges, these measure both pressure and vacuum.

Flow, Pressure, and Temperature Transmitters for Gases
Measure and transmit flow rate, pressure, and temperature of industrial gases, such as air, argon, CO2, and nitrogen, flowing through your system. These transmitters are ideal for applications where temperature and pressure can fluctuate. To calculate flow rate, they generate a small amount of heat, then measure the cooling effect your gas has on it. Also known as transducers, these transmitters convert measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). As flow, temperature, and pressure 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. Mount them directly inline with your system. They measure correctly no matter their mounting orientation.
A digital display makes it easy to read measurements and adjust settings based on your gas. These transmitters have two configurable outputs, and each output can only be wired for one measurement (flow rate, pressure, or temperature). Outputs configured as digital pulse send flow data using spikes of voltage that match the input voltage of the transmitter. One of the outputs can be wired for IO-Link, so you can change settings and receive error messages remotely from your PLC or computer. You’ll need an IO Link controller (not included) to connect to your interface.
These transmitters are calibrated with air but still measure accurately when used with other gases.

Remote-Reading Tension Force Gauges
Safely view your tension force measurements on a handheld receiver up to 450 ft. away when moving bulk material with cranes and hoists. These gauges are also called dynamometers and crane scales. Made of steel, they’re durable enough to briefly hold heavy loads up to 500% of their capacity. But, they will no longer take measurements if the load exceeds 200%. Warning lights will flash first when your load exceeds capacity, then again when it reaches 133% capacity. To prevent overloads, the peak-hold setting displays the highest measurement. The tare function lets you reset the gauge to zero after attaching a container to weigh only the material inside. These gauges include a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They also meet IEC and ASME safety and fatigue standards.
Because their indicators and load cells are IP rated, these gauges stand up to washdowns and brief submersion common to food and chemical plants. They’re also safe to use outdoors since they’re NEMA rated to seal out weather.
These gauges come with two shackles that work with other lifting fittings, such as clevis hooks. The included batteries power their load cells for up to 2,000 hours.
Gauges with a heat shield disc and jacket hold up in foundries and other hot environments because their load cells take longer to reach the maximum temperature than other gauges. An internal thermometer tells you the load cell temperature on the receiver.
