Table 2 Main Software Functions
|
Project |
Explanation |
|
|
Single sampling volume |
It can be set arbitrarily from 10 to 5000mL, with an increment of 1ml |
|
|
Sampling interval |
Set freely from 5 to 9999 minutes, with an increment of 1 minute |
|
|
Sampling mode |
Time ratio, flow ratio, flow tracking, flow start, external control mode |
|
|
Sample retention method |
Synchronous sample retention, over-limit sample retention (analog quantity, switch quantity, and digital quantity can all trigger sample retention |
|
|
Sample supply function |
After the sample mixing is completed, the sample supply pump can continuously provide the online instrument with mixed water samples |
|
|
Automatic pipeline emptying |
After each sampling is completed, the water in the pipeline is automatically drained to prevent cross-contamination during the next sampling |
|
|
Empty the automatic mixing bucket |
After each sample retention is completed, the excess water sample in the mixing bucket is automatically drained to prevent cross-contamination |
|
|
Empty the automatic sample retention bottle |
(Optional) If the water sample in the sample retention bottle exceeds a certain period of time or a remote sample rejection command is received, the water sample will be automatically drained |
|
|
Remote control |
Control instructions can be sent to the sampler through the monitoring platform, data acquisition instrument and industrial control computer to perform corresponding operations |
|
|
Comparative monitoring |
Functions such as comparison monitoring sample retention and parallel monitoring sample retention can be achieved through local Settings or command control |
|
|
Cleaning function |
Automatic pipeline cleaning: It adopts the "blowing - suction - blowing" method to avoid cross-contamination of samples Automatic cleaning of the mixing bucket: Before each sample mixing, the mixing bucket is stirred and rinsed with raw water |
|
|
Switch quantity reverse control online |
When the sample mixing is completed and water samples are provided to the online instrument, the online sample preparation starts through a switch quantity trigger |
|
|
RS485 reverse control online |
(Optional) When the sample mixing is completed and water samples are provided to the online instrument, a command is sent via the 485 network to trigger the online sample preparation, without affecting the normal communication of the original network |
|
|
Mix the bucket to prevent overflow |
The mixing bucket is equipped with an overflow drainage pipeline to prevent water samples from overflowing and damaging the equipment due to sampling errors |
|
|
The sample retention bottle is designed to prevent overflow |
When the sample retention bottle is full, an alarm should be triggered to prompt that no sample should be retained. Only after the alarm is cleared can the sample retention continue |
|
|
The method of dividing water samples into bottles |
Mechanical self-locking position, accurate and reliable, with overload protection |
|
|
External pump control |
The sampling distance can be extended by controlling the external submersible pump or self-priming pump |
|
|
Pre-start the external pump |
