5. How to use the indicator

(1) Installation

Clampon Pig DetectorsClampon Pig Detectors

First fix the Clampon Pig Detector on the pipeline, generally 1 meter to 3 meters away from the receiving and receiving equipment end.

How to use the pipeline clamping mechanism

1) Select the clamping mechanism (clamp) according to the pipeline specification. Fix the card loading mechanism in the desired position. Special Note: Pipelines with insulation. When installing, the sensing mechanism should be attached to the metal pipe wall (see the clamp installation diagram). Insulation after installation.

2) If necessary, the wire connecting the display mechanism and the sensor mechanism can be lengthened (extension rod).

(2) Start the monitoring mode

After installing the No. 5 battery or external power supply and jumping through the jumper cap, the meter starts to run. It shows the current time. The device then enters the calibration procedure. It then automatically detects the threshold, after which it starts monitoring mode. Enter the pig monitoring state. (In order to ensure reliable operation, before each monitoring, run a detection function by pressing the button).

(3) Function description

The meter provides 3 buttons: select button, adjust button and confirm button.
Operation 4 functions: detection function, query function, reset function, time adjustment function.

1. Detection function:

the purpose is to ensure that the battery power supply is normal. Thresholds are adapted to local prevailing conditions. The factory has been set and tested when it leaves the factory. Due to the difference in use environment. Therefore, in order to ensure the accuracy of monitoring, this instrument provides a detection function. The method of use is as follows: first press the selection key. At this time, the detection function light is on. (If you press the selection key continuously, the four function lights will light up in turn. Press the selection key again, and the lights will go out.

At this time, the instrument will enter the pig monitoring state.) At this time, press the confirmation key, and the instrument will automatically enter the detection state. Then the digital tube displays the instrument threshold and set value. Then press the confirm key to exit the detection function. Press the select key again to turn off the function light. The instrument then enters the pig monitoring state. If the function light is on, it is not extinguished by selecting the key. Then the system will automatically turn off the function light if there is no key operation for more than 3 seconds. Finally, the equipment will enter the pig monitoring state.

2. Inquiry function:

Firstly, press the selection key continuously to select the inquiry function. Press the enter key, the digital tube will display the number of passes stored by the meter. Press the confirm key to query the time of the last pig passing. (If the instrument has no record, the digital tube will have no display). By pressing the adjustment key and selecting down, you will inquire about the passing time. If you want to exit the query function, you can press the adjustment key continuously. This will make the number of times displayed zero, and you can exit the query function. At this time, other functions can be selected by selecting the button. Or exit and enter the monitoring state. You can also wait for 3 seconds and then automatically enter the monitoring state.

3. Clearing function:

The meter automatically records the time of each passing. Up to 99 times can be recorded. More than 99 times, the meter is automatically reset. In order to ensure reliable records, effective query. So manual clearing is necessary. Press the SELECT key to select the Clear function. Then press the enter key. After the digital tube displays 00, it will exit automatically. At this time, all internal records have been cleared.

4. Time adjustment function:

If you know or want to see if the time is accurate. Then press the selection key to select the time adjustment function. After pressing the confirmation key, enter the time adjustment. At this time, the hour numerals flash. The hour can be adjusted by adjusting the button (increase only, increment to 24 and return to zero). If the hour display is correct, you can also press the confirmation key to skip to the minute adjustment. At this time, the minute number is flashing, press the adjustment key to adjust the minute. (increment only, increment to 60 back to zero). Press the confirmation key to exit the time adjustment, and the meter will automatically store the set time.

Regardless of the function, if there is no button for more than 3 seconds, the meter will automatically exit all functions. It then enters the pig monitoring state.

(4) Set the Clampon Pig Detector parameters (don’t set it arbitrarily here)

After all the lights are off, press the “Select” key. At this time, the small light of “Detection” will be on, and then press the “Enter” key. The value that appears at this time is the initial magnetic field detection value. The value that appears automatically afterwards is the value set for the instrument alarm. (The initial value of the instrument alarm setting value is set to “160” to adapt to most places, do not adjust it arbitrarily). If adjustment is required: Press the adjustment key continuously and quickly at this time (increase the value by one gear every 4 times).

Then, set the instrument alarm setting value to “160 or other values”. (The value increases by 20 for each change, and returns to 0 after reaching 240, and then continues to increase by 20 for each change). Set the alarm setting value of the instrument to the predetermined value and press the “OK” key to end the operation. The general value of instrument alarm setting value is 160. The smaller the value, the more sensitive the instrument. But its anti-jamming ability is reduced. The higher the value, the less sensitive the instrument is. But the anti-interference ability is improved.

6. Precautions for installation and use

1. Do not hit the display window with heavy objects during installation.

2. Do not use magnetic materials close to the sensor.

3. The pigs that pass the test should have magnetic blocks. If there is no magnetic block, you need to install the magnetic block in the random accessories. Be careful not to collide with the pipeline at the installed position. Operators can install it on the flange or in the middle of the pig frame.

4. The magnetic block is installed on the pig. The preferred orientation of the round face of the magnet is parallel to the base of the sensor. The schematic diagram is as follows:
