Flow sensors provide realtime measurement of fluid or gas flow to support process control and monitoring. Key benefits Accurate flow rate and totalized volume data for process control, inventory, and energy management Quick response with low pressure drop to keep systems efficient Flexible interfaces and materials simplify integration and extend compatibility What it does and how it works Function: measures flow rate (volumetric or mass) and accumulative total; some models include temperature or pressure sensing Compatibility: works with PLCs, SCADA, and building management systems; outputs include 420 mA, pulse, or digital protocols Size and materials: sizes from 1/8 to 2 in nominal; wetted materials include stainless steel 304/316 or robust polymers Performance: typical accuracy from 1 to 3 percent depending on model; fast response; low pressure drop Installation: inline, clampon noninvasive, or insertion configurations Practical use scenarios Building HVAC: monitor chilled water or air flow to optimize energy use Industrial processing: track reactant or solvent flow in a closed loop Food, beverage, or pharmaceutical manufacturing: ensure precise dosing and inventory control Maintenance and calibration Factory calibrated; field recalibration available; rugged design for long life
