6、 Key points and steps for installation and debugging:
1、Select probe from the menu: Ultrasound → Ultrasonic transducer Or 4-20mA input

2、Choose weir channel and flow measurement unit:
(1) Paxie slot, rectangular weir, equal width weir, triangular weir, and input the corresponding weir slot size into the instrument. After selecting the weir slot, press and hold the confirm button to display the size interface

(2) Flow measurement units: KG, m3, L, T

3、Flow level measurement:
Flow level measurement is a necessary condition for the normal operation of instruments Emphasizing the importance of "air distance", only when the air distance is accurate, it indicates that the instrument is normal, and the rest of the work is much simpler

4、If there is still instantaneous flow display without sewage flow, increase the number of "water level cut-off" and decrease the number of water level cut-off

7、 Analysis of reasons for abnormal instrument:
A、Liquid level display → "echo loss" or "FFFFFF" → indicates that the instrument has not received an echo
1、There are abnormalities in the wiring between the probe and the instrument: carefully check whether the connecting wires are reliable, whether there are any broken wires inside the wires, and if necessary, temporarily replace the external wiring and try it out
2、The surface condition of the measured liquid is complex (for example, there are a lot of foam and floating objects on the liquid surface), which leads to the poor reflection ability of the water level surface → clear the foam and floating objects

B、When the liquid level changes, the air distance (liquid level) display number does not change
1、The liquid level height enters the blind zone of the transducer → raise the position of the ultrasonic transducer
2、The diameter of the static water well is too small or there is dirt or poor edge flatness inside the static water well → Increase the size of the static water well, clean the dirt or use a static water well material with smooth inner walls Change the installation position until the air distance stabilizes

C、Display numbers with regular back and forth movements (characteristic: one of the numbers is fixed and unchanged)
1、There are relatively weak false targets above the measured sewage, which generate false echoes (sometimes absent), such as uneven height inside the static water well, and serious scaling on the inner wall of the clean water well after long-term use
2、We can determine whether the digital jitter interference comes from the outside or the instrument itself by using the following method: facing the ultrasonic transmitter towards the open sky, theoretically speaking, the instrument will not receive any echo at this time, and the instrument water level will prompt "echo loss" or "FFFFFF", indicating that the interference is from outside On the contrary, the digital jumping comes from the instrument itself and needs to be returned to the manufacturer for maintenance

8、 Wiring, external dimensions, and accompanying drawings:

6000CMG wiring instructions:
Using a four core shielded wire, the shielding layer is connected to the instrument ground GND at one end.
