Turbine 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.

Turbine Flow Measurement—Turbine transmitters measure flow by counting how many times their turbine turns as liquid passes through. To avoid clogging the turbine and other damage, use them only with clean, low-viscosity liquids. The digital output sends flow data with a pulse, which is a spike of voltage. The higher the flow, the more pulses they send. The voltage of the pulse output matches the input voltage sent to the transmitters. These transmitters meet NSF/ANSI 61 for use with drinking water.

Flow Transmitters with Sight

Send flow rate data using these transmitters while also being able to visually confirm liquid is flowing. They measure flow by counting how many times the turbine turns as the liquid moves through it. To prevent clogging the turbine and other damage, use them only with clean, low-viscosity liquids. These transmitters, also known as transducers, convert the flow measurement 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. Mount them directly inline with your system. They measure accurately in any 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.

Digital Pulse Output—Transmitters with a digital pulse output send flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send.
