## Description

This Gravity: liquid flow sensor is designed based on the electromagnetic principle. It adopts an O-ring rubber seal and uses silicone sealant at the outlet end to strength water-resistance. With high anti-interference and anti-impact, the sensor offers reliable performance and long service life. Also, it is designed with G1/4 thread connectors for easy installation.The sensor can be used with microcontrollers like Arduino UNO to measure the flow of liquids with high concentration and low viscosity like water, diesel, engine oil, milk, paint, detergent, honey, etc. (no impurity in liquid)FeaturesGravity connector, easy to wireWide voltage of 3.5-24VSupports measuring liquid with high concentration and low-viscosity RoHS compliant ApplicationsMeasure the flow of liquids with high concentration and low viscosity SpecificationOperating Voltage: DC3.5-24V Operating Current: ≤10mA (DC5V) Output: NPN Pulse signalPipe Diameter: G1/4Thread Outer Diameter: 13mmThread Length: 10mmWater Pressure Resistance: ≤1.0MPAInsulation Resistance: >100MΩError: ±1%(0.3-5L/min)Output Pulse High Level: >DC4.7V(Input voltage DC5V)Output Pulse Low Level: Output Pulse Duty Ratio: 50%±10% Flow-Pulse Correlation: 1L=540 pulses Operating Temperature Range: -10°~70°C Operating Humidity Range: 35%~90%RH(No condensing) Storage Temperature: -25°~+80°C Storage Humidity: 25%~95%RH Dimension: 80*47*30mm/3.15*1.85*1.18” DocumentsProduct wikiShipping ListGravity: Liquid Flow Sensor (G1/4) x1
