Low Flow Divided Type Electromagnetic Flow Meter Ex-proof JIS 10K Flange
 
 

Instrument characteristic

1). No baffles and running part inside the measuring tube, therefore no additional flow

loss and no jams happen. Especially for measuring the flow of solid-liquid object, for

example, sewage, mud pulp and CWS (coal water slurry).

2). Only liner and electrode have direct contact with the measuring medium, by

choosing correct liner and electrode,,then the corrosion resistance and wear resistance

can be satisfied. Therefore it can be used in kinds of strong acid and alkali in chemical

solutions.

3). Easy for installation, 5D for front straight pipe, 2D for back straight pipe(D means

inner diameter of chosen instrument).

4). High accuracy, it is up to ±0.2%,it is capable for testing

5). It provides the function of zero correction of sensor and automatic zero adjustment.

6). It has multi-language interface to satisfy all the users’ requirements.

7). It has the function of self-adjustment and self-checking.

8). It has lightning-protection and electricity-protection circuits. The effective,

anti-interference circuits apply to all kinds of bad environment.

Measures in the following failures:

1. No display

a) Check if the power supply is OK;

b) Check if the power fuse is OK;

c) Check if the power voltage is OK;

If the above is OK, please send the converter to the repair shop.

2. Excitation alarm

a) Check if the wiring X and Y is open;

b) Check the coil resistance, if normal, the converter should have failures.

3. Empty pipe alarm

a) Check if the fluid is full of the measuring pipe of sensor;

b) Input the converter signal to A, B, C terminals with wire, if “empty pipe alarm” disappears, it shows the converter is OK. But maybe the conductivity of measured fluid is too low or the measuring range setting of empty pipe is wrong;

4. Inaccurate flow

a) Check if the fluid is full of the measuring pipe;

b) Check if the signal connection is normal;

c) Check if the setting of coefficient and zero is in line with the requirements in label.
