SBJ-80︿250 Cubic measurement instrument for water meter
Function:
The function of this product is for secondary display of far-transmitted water usage in long distance
Characteristic：the product is consisted by electronic counter, electronic-controlled calculation circuit. The whole circuit is CMOS circuit. Outer covers are made with high-density ABS engineering plastic materials. The instrument box is very convenient for installation and application with clear reading; 5V pulse output is provided ad connected with computer.
Main technical parameters：

SBJ-150︿250 1︿999999 m3
2.Power supplied：220V ±10℅
50HZ ±10℅
3.environment temperature：20°C︿+50°C
4.relative humidity：30︿85℅
5.output values：5V ±5℅
6.fux parameters：to be determined by matching water meter
7.basic error：≤1%
Installation requirement:
1. The specification of the instrument should be the same with the caliber of water meter, and installed in the form of cabinet. The surrounding environment should be free from disturbance of electrical magnetic field.
2. transmission cable are three core shielded leads, and the installation location should be free from electrical magnetic field.
Far-transmitted three core cables of water meter should be fixed at the dry place after connected with transmission cable. After installation finished, check whether the transmission cables are correctly connected or reliable. After that, It's ok to connect the three core cables into those cables in the far-transmitted water meter and four cores cables into those cables in the cubic measurement instrument. Once the power is connected, the water is passing through and operation starts
Outer dimension： 163×83×123

Failure removing：
1.220V power is not correctly connected. At that time, the power light is off
2.The surrounding of cubic measurement instrument is disturbed by high electric magnetic fields.
3. Connection of three core cables for signal transmission is wrong, or leads disconnect or in short circuit. The cable plugs (pins) are immerged with water. At that time, the operation light is not flashing.
