![]() Several factors may impact measurement accuracy. Troubleshooting Tips for Inline Water Flow Meters Ensure there is a periodic maintenance schedule set and followed.Train the personnel to handle and operate the meter in the.Ensure the controls and functions of the meter are functioning correctly and that the attached device is responding appropriately.Perform an inspection by sending fluid through the lines and checking for proper operation and pulse output.Calibrate and configure the inline flow meter depending on the size and speed of fluids passing through it, temperature requirements, flow rate requirements, and other parameters.Install any software or control systems and ensure the wiring is correctly connected. Connect the meter’s sensor wires to the input of the measuring device as per the manufacturer’s guidelines.Ensure the fittings are tight and there is no leakage.Mount the flowmeter in the location, and connect it to the pipeline using the required seals, gaskets, and fittings.Depressurize the pipeline and ensure there is no contamination or dirt in the flow path around the meter.Ensure the upstream and downstream pipe length as well as the pipe diameter meets the requirements.Rotate the meter manually to view the scale depicting the water flow.Connect the meter to the piping system via a wrench on the same side as of the pipe connection.It should be easily accessible and visible for future maintenance and reading. Mount the flowmeter with consideration of the direction of the flow.Installation steps for the WFM inline water flow meters. Installation and Maintenance of Inline Flow Meters This value determines the volume of water that has passed through the meter. This position of the magnetic dial can be seen by the user on the volume display on top of the meter. This movement is directly proportional to the water flow rate in the water. There is a magnetic dial connected on the outer side of the magnet, which moves with the spinning magnet. Connected to a magnet, the impeller rotates with the spinning of this magnet. They have multiple ports which create water flow at required rate and directions. ![]() The WFM meters are velocity type meters with an impeller that rotates at a certain speed. It needs to be wired correctly to your remote device. When operating the multi-jet meter, you need to set the volume per pulse rate and note the position of the magnet pointer. All these models have inlet and outlet ports and units with a sensor have a color coded output cable. Totalizing-only models do not require a sensor. Our WFM series inline chemical flow meters, depending on the model, may use either a solid-state Hall effect sensor or a reed switch. These chemical feed flow meters have a gear train that drives the register totalizer dials. The WFM inline flowmeters operate on the multi-jet principle. A gear train drives the register totalizer dials and magnetic indicator to send pulses proportional to the volume. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. ![]() 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. They have a pulse output that provides a signal to a controller or to a metering pump for proportional chemical feed. They are available in 3/4″, 1″, 1½” and 2″ NPT sizes for flow rates from 0.22 to 132 GPM. Our collection features the WFM series of flow meters that work on the multi-jet principle to provide dependable, accurate performance. Walchem offers various types of inline water flow meters for water treatment and related applications. 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. This style of flow meter is typically installed permanently in a process line. It has a built-in flow stabilizer that controls and steadies the flow profile of the process fluid.
