Using high-quality materials, the quality is guaranteed. Real-time synchronous feedback of remote output status and water levelIt can run independently without WIFI, and realize the function of single-machine control of water level. The on-off of one output can be controlled remotely or manually on site (when the set water level value is not reached)It can control drainage with high opening and low closing, or control water replenishment with low opening and high closing, or select time-limited control mode. Remote and lower water level alarm APP push function. APP can display the current water level, start water level, stop water level, and lower limit alarm water levelTwo outputs, one water level control, one anti-dry function. The main account can share the device with others, and the device can only be added under one main account (note that the alarm can only be realized if the device and the mobile phone are both online. Without , it is like the mobile phone can' make a call without a signal )Interface size: 4 points (G1/2)Operating voltage range: DC5 ~ 15VInner/Outer Diameter: 10.9mm/20mmThread length: 14.5mm12.5mmWater pressure resistance: less than 1.75MPaOutput pulse high level: DC4.7V (input voltage DC5V)Output pulse low level: Less than DC0.5V (input voltage DC5V)Insulation resistance: 100MQFlow range: 1~30L/MINAirtightness: each hole, add 1.7Mpa water pressure test for 1 without leakage and deformationFlow pulse characteristics: F= (7.5*Q) error less than 3%Appearance size: 89x55x44mmInstallation and size: standard 35MM rail installationWorking power and power consumption: AC220V; Less than 2WWater level display: five-level water level display: 0%, 25%, 50%, 75%,100%Water level control range: full water level: 25%, 50%, 75%, 100% make-up water level: 25%, 50%, 75%, 100%Time limit range: 0-720 minutes, need to be set on the APP, step by 5 minutes to setRelay life: 100,000 Operating environment: -10Celsius~50CelsiusWireless standard: WIFI2.4GHZ B/GParameter memory: long-term memory of setting parameters when power off, can run offlineColour:As shownMaterial:plasticPackage Contents:1 x Water level controller5 x Water level electrodeOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
