The unit is battery powered, and no electrical connections are necessary. Each unit is supplied with a calibration certificate for high purity water and interconnecting cabling between the flow and readout module. Flow Module The flow module is a positive displacement flowmeter designed for the measurement of very small flow rates in applications requiring high accuracy. It allows remote registration and totalization using a reed switch output. Each flow module is equipped with two oval shaped gears which rotate when fluid passes through a fixed measuring chamber. Rotation of gears displaces a fixed volume of fluid. The sensor picks up gear rotation, which is proportional to fluid volume and flow rate. The meter is designed to minimize slippage between the gears and measuring chamber body. As a result, the meter is less affected by liquid viscosity and lubricity than other flowmeter designs.
