[Non-Contact Ultrasonic Flow Measurement]:This handheld ultrasonic flow meter uses non-contact measurement technology that simply attaches to the outer pipe wall unlike inline meters requiring no pipeline destruction or production shutdown for easier flow testing in factories [Clip-On Sensor for Quick Setup]:Features a magnetic clip-on water flow meter sensor that securely attaches to the pipe exterior enabling faster installation than strapped sensors while maintaining accurate readings throughout your measurement session [High Measurement Accuracy ±1%]:Delivers better than ±1% measurement accuracy with linearity and repeatability of 0.5%±0.2% making this portable clamp on flowmeter more reliable than basic models for precise flow monitoring in industrial environments,Applicable pipe materials: steel, stainless steel, cast iron, PVC, fiberglass and other uniform and dense pipes. [12-Hour Rechargeable Battery Operation]:Built-in rechargeable battery supports continuous operation for more than 12 hours giving you longer field work time than meters with shorter battery life for convenient use in shops or factories [Wide Industrial Application Scope]:Suitable for production monitoring flow calibration temporary detection and water meter debugging across tap water heating water conservancy metallurgy chemical and energy industries making this clip on ultrasonic flow meter an essential water flow detection tool
