Compatible with Arduino, Raspberry Pi, and reverse osmosis filters, it operates on a wide voltage range (DC 5-18V) and withstands pressures up to 1.75 MPa. Its waterproof, heat-resistant design and ROHS-certified materials make it ideal for potable water applications in smart home and industrial setups. ## Description Specifications:Frequency: F=5.5 * Q (L / Min), error: ± 2%, current can not exceed 10mA, 330 pulses/liter. F=onstant * units of flow (L / min) * time (seconds).Flow range:1-60L/minMaximum current:10 mA(DC 5V) Working voltage range:DC 5-18 VLoad capacity:≤10 mA(DC 5V) Operating Temp: ≤80℃Operating humidity: 35％ - 90%RHAllow compression:Water pressure 1.75 Mpa below Insulation resistance: >100M OHMStorage Temperature:-25℃～80℃Storage humidity:25%～95%RH Output Waveform:Square Wave,output pulse singal.Cable length:15cm.Package include: Flowmeter x 1 Review: Extremely annoying that every water flow sensor I've found on desertcart has BSPP or BSPT threads. Why aren't there any NPT options? Yes you can buy an adaptor but the adapters cost more than the flow sensor and add multiple connections otherwise known as points of failure/leak potential, not to mention the extra cost and work to install. To add to the problems the flow sensor arrived with a corner of the housing broken off, bad packaging and poor handling by the shipper which is not surprising since almost all my deliveries get thrown onto my porch by the delivery person, they really don't care. I don't even know if this device works or how well it works because I'm not prepared to spend more than double the cost of the sensor on adapters just so I can install/test it. Update: I needed to get a solution working so I spent $40 on BSPP to NPT adapters and then found that the length of the threaded portion of the adapters is longer than the threaded portion of the flow sensor and does not allow the ends to 'seat' and form a water tight seal. Packing in rubber washers helped a little but it still leaks. I've now wasted even more money and don't have a working solution. This is ridiculous! Review: Das Produkt kann ich nicht bewerten, da es nicht gepasst hat. Abmessungen mitzuteilen wäre hilfreich. ## Features - ☺Work for Arduino, Raspberry Pi, and Reverse Osmosis Filter. Small size, waterproof, easy to install, heat resistance, pressure resistance, cold resistance. - ☺Material: food grade, all materials are in line with ROHS testing standards, can be used for potable water. - ☺Cable length: 15cm. Flow range:1-60L/min, working voltage range:DC 5-18 V, allow compression:Water pressure 1.75 Mpa below. - ☺Hall effect sensor. Connect to G3/4 inch BSPT male thread, if used for NPT, need thread seal tape.
