It accepts a 1-inch female NPT connection and handles flow rates up to 21 GPM at a maximum working pressure of 125 psi. The vertical-mount design keeps the float tube properly aligned for accurate readings. With an accuracy rating of 0.03, it delivers reliable measurement for applications where consistent flow monitoring is required. Plumbers, HVAC technicians, and industrial maintenance crews install this type of meter on water supply lines, chiller loops, and process water circuits.\u003c\/p\u003e\u003cp\u003eThis flowmeter is suited for residential and light commercial water systems where a direct-reading, in-line flow measurement is needed. The clear acrylic housing allows for immediate visual confirmation of flow rate without additional instrumentation. It installs in a vertical orientation on any water line using standard 1-inch NPT threaded fittings. The PVC fittings are compatible with typical water service piping. General-purpose water service is the primary application, making it a practical choice for balancing hydronic loops, verifying pump output, or monitoring service flow during commissioning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21 GPM maximum flow capacity for general-purpose water measurement\u003c\/li\u003e\n\u003cli\u003e125 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003e1-inch FNPT connection fits standard water service pipe sizing\u003c\/li\u003e\n\u003cli\u003eClear acrylic housing provides direct visual flow reading\u003c\/li\u003e\n\u003cli\u003e0.03 accuracy rating for reliable flow verification\u003c\/li\u003e\n\u003cli\u003eVertical mounting orientation ensures float tube alignment and measurement integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose water service applications using 1-inch NPT threaded connections in vertical-mount configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified mechanical technician. Shut off the water supply and depressurize the line before threading the meter into the circuit. Mount the unit in a true vertical position — off-axis mounting will affect float movement and measurement accuracy. Apply thread sealant or PTFE tape to NPT threads per standard plumbing practice and verify no leaks before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 21 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Thread Style\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.03\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Acrylic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Acrylic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Polyvinylchloride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Water\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7205018131W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KING TECHNOLOGY","offers":[{"title":"Default Title","offer_id":51703178592562,"sku":"7205018131W","price":294.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af936725353a5744a35040c38c0f6c66.jpg?v=1788415251","url":"https:\/\/voomisupply.com\/products\/king-7205018131w-tube-flowmeter-21-gpm-1-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
