FC-2024AB Automatic water sampler

The FC-2024AB dual mixing box water quality automatic sampler is designed in accordance with the new environmental protection standards HJ 353-2019 and HJ 355-2019. It can collect instantaneous water samples and mixed water samples to supply the water quality analyzer (CODCr, ammonia nitrogen, total phosphorus, total nitrogen......) Measurement, etc.
Online monitoring of water pollution sources, municipal sewage discharge outlets, industrial wastewater discharge outlets.
Product features：

· Provide instantaneous water samples and mixed water samples for the analyzer;

· Large-capacity AB double boxes, each box over 5000ml, corrosion-resistant;

· Self-developed, modular design, highly integrated, low failure rate, and simple and convenient maintenance and repair.

· The power-off normally closed electric control door lock can achieve door opening and closing record and remote control, which is convenient and reliable.

· The printer outputs the current program and sampling results.

· The 7-inch true-color touch screen makes program Settings as simple and clear as using a mobile phone.

· The glass door facilitates the observation of the internal operation of the instrument.

· The AB double boxes and 24 sample bottles are all placed in a 4±2° constant temperature refrigerated box with an electrically controlled door lock to ensure the safety, consistency and non-deterioration of the water samples.

· It can be interconnected with analyzers from various domestic manufacturers and has strong adaptability.

· An optional smart cloud management platform is available.

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

Before starting the sampling pump, the external submersible pump or self-priming pump can be started in advance through the preset time

Water samples are stored at a constant temperature

The temperature range is adjustable from 2 to 8℃, with digital display

Power-off protection

After power failure and restart, the stored parameters and data will not be lost

Printing function

(Optional) The micro printer can print the stored and recorded data

Electronic access control

Prevent non-staff members from manipulating the stored water samples

Software password lock

Prevent non-operating personnel from making mistakes or engaging in malicious operations

Voice broadcast
