![]() The alarm used to detect paddle damage or loss is intended to assist on-site operators to find out what is causing equipment abnormalities. LORRIC assumes no responsibility or liability for any omissions or errors in connection with the use of its products. The purchaser must determine the applicability of the product for its desired use and assumes all risks in connection therewith. *DISCLAIMER: Please be aware that magnetic fields or residual magnetism may cause interference to the flowmeter which may result in damage if they are used near the installation site. LORRIC paddle wheel flow meter equipped with the patented axlesense design, when paddle disappears, it can detect give the corresponding warning, so the better field management can be realized. Lorric’s paddlewheel flow meter equipped with patented AxleSense technology, can detect paddle disappearance by displaying a warning signal (flashing bright red light) on the operational screen. The filter installed after the flowmeter can prevent downstream equipment (ex: pump) from being damaged by any falling parts. The filter installed before the flow meter can filter impurities or foreign objects from sticking on the blades that make it unable to rotate. Filters Installed Before and After the Flow Meterįor longer service life and better measurement accuracy for the paddlewheel flow meter, we suggest setting filters or related technology before or after the flowmeter. This recommendation is also applicable to other piping components that may affect the flow field.ģ. ![]() The flow meter should be installed upstream of valve, so the fluid will be fully developed. Install the paddlewheel flowmeter before the valve. If the inside of the pipe diameter is unknown, the outside of the diameter can be used.Ģ. Generally, it is recommended that the flowmeter be installed at a position 10D (10x inside diameter of the pipe) at the front and 5D at the back (as shown in the figure below). There should be at least 10D (10x the inside diameter of the pipe) of straight pipe in front of the flowmeter and 5D of straight pipe behind the flowmeter to stabilize flow.ĭuring flow movement, where the liquid is coming from means the front and where it’s moving to means the back. Tips for installing a paddlewheel flowmeter correctly.ġ. However, accurate flow measurement is attainable with a fully developed and stabilized flow. At this point, measuring flowrate is unpredictable and difficult. The initial flow will be a mixture of dual flow directions which inevitably leads to unstable flow speeds. Stable flow field makes best accuracy of flow measurement. Through Lorric’s decades of on-site experience, we will provide recommendations to increase the accuracy of your flowmeter. Please see below for a simple guideline on how to correctly install a flowmeter either vertically or horizontally. ![]() To avoid this, Lorric recommends to carefully choose a suitable installation location. Factors that could affect accurate flow meter measurement, but not limited to impurities, pressure, water volume and bubbles.
