The microFlow.net Liquid is a microprocessor-based, explosion-proof electronic flow computer with Ethernet that monitors and controls a single liquid meter stream. It operates stand-alone or as part of an automation or SCADA system, and provides temperature, pressure and density compensation, a ten-point meter factor curve, dual-pulse security, configurable batch reports, event logging and audit trail. It can control up to four additive injector systems (metered, piston or smart additives), supports samplers and sediment-and-water monitors, and communicates with Smith Meter Ultra Series liquid ultrasonic meters.
