Flow Monitoring

Socket-Connect Flowmeter/Totalizers
with Remote Display

Often used in hard-to-access areas, these flowmeter/totalizers have a display that can be placed up to 25 feet from the sensor. They connect to unthreaded PVC pipe.

Flow Transmitters with Sight

Send flow rate data using these transmitters while also being able to visually confirm liquid is flowing.

Noncontact Flow Transmitters

Using ultrasonic waves, these transmitters measure the flow rate of your liquid from outside your pipe.

Ultra-Low-Flow Flow Transmitters

Often used in low-flow metering applications for lubricants or antifreeze, these transmitters measure flow rate and send the data to a remote display or programmable logic controller (PLC).

Flow Transmitters

Send flow rate measurements to monitor and control equipment.
