    Fixed-Set-Point Flow Switches for Drinking Water

    Image of Product. Front orientation. Flow Switches. Fixed-Set-Point Flow Switches for Drinking Water.
    Factory set to activate equipment when your drinking water system reaches a fixed level, these flow switches are easier to install than adjustable flow switches. They meet NSF/ANSI 61, so they're safe to use with drinking water. They actuate when your system’s flowing water pushes their paddle into a set position. These switches are single pole, single throw (SPST) and turn one device from off to on. IP rated, they seal out dust and can be lightly rinsed. They're accurate in any mounting position.
    These flow switches 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.

    Flow Transmitters

    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.

    Sanitary Electronic Insertion-Mount Flow Switches

    Image of Product. Front orientation. Flow Switches. Sanitary Electronic Insertion-Mount Flow Switches.
    Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.
    They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. They’re accurate in any mounting position.
