The F-44750LK-12 flow meter is made specifically for highly corrosive substances. Made from polysulfone to resist high temperatures and pressure. These meters arepact, designed to fit into tight installations. Flows from 1.0 to 10.0 GPM (5.0 to 37.5 LPM). With 3/4" pipe size, Hastelloy float material.In more recent years, flow meters have developed with modern technology, sporting digital readouts, high-tech sensors, and more. We believe that they will be easier to use remotely, using wireless internet, perhaps acting as smart meters. All flow meters will also likely have no moving parts at some point in the future.Coriolis. DP Meters. Magnetic Meters. Multiphase Meters. Ultrasonic Meters. Vortex Meters. Coriolis meters are generally considered the most repeatably accurate flow meters available today. Coriolis meters are ideal for any application where high accuracy is a key factor for consistent product quality, safety and revenue.A Digital Water flow meter is a flow meter that can display the water flow rate, and have the output for the flow rate. Like 4-20mA output, HART, RS 485, and so on. Digital Water Flow Meter is widely used in industrial water and household water measurement. Most of the Sino-Inst flow meters are digital water flow meters.
