Products Description
VIEWSHINE Cold Water Meters With Pulse Output is an innovative civilian water meter product that integrates advanced wireless communication and cutting-edge data analysis technology, with three wire pulse output communication function. It adopts an innovative engineering plastic structure and is equipped with an ultrasonic sensing system with zero moving parts, achieving a long service life of up to 12 years. Throughout the entire usage cycle, it can maintain high-precision measurement of ± 1% without the need for maintenance. Through LoRaWAN/NB IoT dual-mode transmission technology and machine learning water analysis engine, this pulse output water meter, with its extremely high accuracy and excellent efficiency, can significantly reduce costs in water billing and management work. It can accurately detect water waste phenomena, detect leakage problems in advance, help users develop reasonable water usage habits, and effectively reduce operating costs. This water meter can withstand a maximum pressure of up to 16 bar and has successfully passed MID B+D certification, OIML certification, and WRAS certification, with reliable quality.
Main Features
1. All solid state high reliability: designed with zero mechanical moving parts, completely eliminating interference from water impurities, with a service life of up to 12 years, stable and durable without any worries.
2. Ultra wide dynamic range: Covering the dynamic range of R400, it can accurately measure both small and large water flows.
3. Micro flow start-up high sensitivity: The initial flow rate is as low as 10L/h, which is significantly higher than traditional mechanical water meters, and can sensitively capture even subtle water dripping from faucets.
4. Complete international certification: Strictly comply with OIML U0/D0 standards, pass IP68 certification in 0 ℃ -50 ℃ environment, and obtain international authoritative recognition for quality.
5. Data intelligence configurable: Supports storing 64 types of event logs, covering situations such as water leakage, magnetic attacks, and pressure anomalies, with a flexible and adjustable storage period of 1-36 months.
6. Extreme environmental adaptability: The fully sealed injection molded shell has been tested for 72 hours at a water depth of 30 meters and can still operate stably in harsh environments such as sand, cold, and corrosion.
