Dry dial water meter WFM

multi-jet vane wheel

An inline flow meter measures the volume of fluid moving through a pipeline. It has a built-in flow stabilizer that controls and steadies the flow profile of the process fluid. This style of flow meter is typically installed permanently in a process line. This meter does not require a straight run and hence allows the user to shorten the length of the upstream straight run, depending on the pipe diameter. Walchem offers various types of inline water flow meters for water treatment and related applications. Our collection features the WFM series of flow meters that work on the multi-jet principle to provide dependable, accurate performance. They are available in 3/4″, 1″, 1½” and 2″ NPT sizes for flow rates from 0.22 to 132 GPM. They have a pulse output that provides a signal to a controller or to a metering pump for proportional chemical feed. WFM Series water meters have earned a reputation for having a simple, yet robust, design, fit a wide range of applications and maintain accuracy in low-quality water. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials and magnetic indicator to send pulses proportional to the volume. Key Features: • Simple and dependable multi-jet design. • Available in 3/4”, 1”, 1½” and 2” NPT sizes for flow rates from 0.22 to 132 GPM. • A wide range of pulse rates for a variety of applications. • Reed switch or Hall effect sensor options.
