Flow MetersMeasure the rate and total volume of liquids, gases, and steam moving through process piping with instruments that help operators control batches, track inventory, and improve efficiency. Our flow meter catalog spans magnetic, ultrasonic, turbine, vortex, and Coriolis technologies for virtually every fluid and pipe size.
Flow SensorsContinuous flow data is the foundation of modern process automation, and our flow sensors provide it across a wide range of pipe sizes and fluid types. Paddle-wheel, thermal, magnetic, and ultrasonic technologies offer the right balance of accuracy and cost for every application.
Flow SwitchesWhen fluid movement falls outside set thresholds, flow switches trigger alarms or shutdowns that protect pumps, heaters, and cooling systems from costly damage. Mechanical, thermal, and ultrasonic models support insertion and inline installation in pipes of every size.
Flow TransmittersIntegrate flow measurement with PLCs, DCSs, and SCADA systems using transmitters that convert raw sensor signals into standardized 4-20 mA or digital outputs. Pair these instruments with magnetic, vortex, or differential pressure elements for a complete flow-monitoring solution.
