Bubble type liquid level gauge
AMT-YW103 is suitable for continuous and accurate water level measurement in the environment, because there is no need to build a water level well, for hydrology station water level, reservoir water level, dam pressure pipe and upstream and downstream water level monitoring, bubble type water level meter is one of the most ideal water level monitoring instruments. It has the characteristics of easy installation and maintenance, flexible operation, stable and reliable operation and high precision. The water level gauge uses the core as a high precision pressure detection unit. The pressure measurement accuracy is 0.05%, with low power consumption, anti-corrosion, anti-radiation, anti-interference, long-term pressure and other advantages.
Power supply, communication and other ports have lightning protection function;
There is no need to build logging, and the gas pipe joint is selected as a pagoda joint, which is convenient, reliable, easy to install, use and maintain:
Two-stage one-way valve, automatic constant air pressure;
Two-stage air chamber (chamber) buffer one air chamber inside the water level gauge and one at the end of the water inlet pipe to buffer the instantaneous air pressure;
Automatic fault detection: core failure, gas pipe blockage, gas leakage, pressure timeout, high water level, low water level, low power supply voltage automatic detection and upload;
Sensor selection of high-precision core;
Ultra-low power consumption: static current less than 3.2mA Wide voltage: 10VDC~14VDC. 830V input can be customized;
Wide range: 0~20m,0~40m optional, or other specifications;
Multi-communication mode: Standard digital quantity: 485(MODBUS_RTU protocol); Analog (optional) : 4~20mA;
Multi-working mode: Mode 0 timing collection, can achieve ultra-low power consumption, set the working interval and working time of the air pump to ensure real-time data while minimizing power consumption;
Mode 2 button or host computer command collection, convenient field debugging;
Embedded clock module;
2.5M bytes of solid state storage: 20,480 sets of data with a time label can be stored, if saved twice a day, it can be stored for 28 years. Cyclic storage;
Software and buttons can be set: working mode, liquid density, acquisition timing, trigger interval, air pump time limit, stability time, monitoring time limit, monitoring amplitude 485 communication address and other parameters can be set through software and buttons.
During the collection period, button operation is prohibited;
Chinese LCD display: when collecting, automatically light up the display; Press any key to open and close the display, and turn off automatically after 5 seconds of no operation under the lit state; After 1 second of no operation, exit the setting and the screen closes.
