Water level indicator

technical parameter
Mounting hole size: 111 x 111mm.
1, water level range: the same as the sensor (10m, 20m, 40m, 80m, etc.)
2, resolution: same as sensor (1cm, 1mm, etc.)
3, measurement accuracy: the same as the sensor, that is, + 0.1% x range + 1cm (or 1mm).
4, display mode: 6 bit plus 2 bit LED display. The 6 is absolute water level (4 bit relative water level, +6 bit elevation), showing (red), word height 0.56". 2 for communication station number or as other symbols (green), word height 0.3".
5, the connection between sensor and display: multi-core cable (14~20 core).
6, input code system (sensor output code): cyclic code (Ge Leima) or other code system (to be customized).
7, the distance between sensor and display: up to 2km.
8, data remote transmission mode (optional):
1) RS-485 (type XZ-1A), using a pair of twisted pair transmission networking. Data remote transmission distance: 1.2km.
RS-485 port communication protocol: 1) MOD-WS1 (MODBUS); 2) SDI-12.
2) 4~20mA current loop mode (type XZ-1B), with a pair of wire transmission.
The above data does not contain elevation values
9 、 current loop: resolution: same as sensor; nonlinearity: MAX + 0.012%; maximum error: + 0.15%
10, manual preset function
1) lower limit preset: zero at the factory. (4, without elevation)
2) upper limit preset: the maximum opening value at the factory. (4, without elevation)
3) preset preset: the maximum opening value at the factory. (4, without elevation)
4) altitude preset: zero at the factory. (6 digits)
5) range (type XZ-1B only): range (4 bit, without altitude)
6) communication station number preset: usually set to 01 at the factory.
11. Alarm and control function
Alarm control signal: relay contact. Contact capacity: 1A24VDC, 0.5A125VAC.
When it is greater than or equal to the upper, middle and lower or lower limits, the relay contacts attract, and the sound and light alarm (the decimal point flashes in the data area). The duration of the sound alarm is about 10 seconds. Only relay action in the middle limit.
12, display and sensor coupling: photoelectric isolation
13, work mode: continuous work.
14, the display single chip microcomputer plus Watchdog, in order to prevent the operation of the accident.
15, working environment temperature: 0 ~ +50 centigrade, relative humidity: 85% (+25).
16, power supply: 120VAC~ 264VAC, 47~440Hz. Power consumption: <5W. Fuse 2A.
17, size: 120 x 120 x 120mm.
