Flow and Temperature Transmitters

Variable Area Flow

Measurement

Send flow rate and temperature measurements simultaneously to a programmable logic controller (PLC), data logger, or other receiving device. Used to monitor status or control equipment, these transmitters, also known as transducers, convert measurements to an electrical signal that is interpreted by receiving devices. 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. Mount them inline with your pipe system. They’ll measure flow correctly in any mounting orientation.

A digital display makes it easy to view readings and adjust settings at the source. To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You’ll need an IO Link controller (not included) to connect to your interface.

Variable Area Flow Measurement—Variable-area transmitters determine the flow rate by tracking where the liquid pushes the piston. They have two configurable outputs. One can be wired as an analog output or a digital switch. The other one can be wired 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. These transmitters are calibrated with water, glycol solutions, and coolants but can be recalibrated in the field for other liquids.

Flow Measurement

Send flow rate measurements to monitor and control equipment. Also known as transducers, these transmitters convert flow rate measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). As flow 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 flow correctly no matter their mounting orientation.

These transmitters 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.
