Domestic portable open channel flowmeter XY-6800R portable sewage flowmeter

I am a salesperson for environmental instruments and meters. Time passes quickly every day and I feel like it's not enough. Every morning, I wake up at 5:20 and start cooking for Da Bao. Da Bao eats at 5:45 and goes to school for morning classes at 6 after meals. At 6 o'clock, I start cleaning myself up, and then I start cooking around 6:40. After 7 o'clock, I finish cooking and wake up Er Bao to eat. At 8 o'clock, I send Er Bao to kindergarten, and then I come to the company to work on my own. This is a stormy morning.

After starting work in the morning, I found out that there was a missed call at 10 o'clock last night. I quickly called the customer and they said they needed personal protection and equipment. We communicated for more than an hour about the configuration, size of the trolley box, shipping costs, and so on. We haven't finished our work yet. A customer from Guizhou who wants to install a mercury analyzer online sent me some technical parameters. I quickly confirmed the price and configuration for the personal protection box customer and started the technical comparison of the online water quality detector. After comparison, the customer needed a anodic dissolution voltammetry online mercury analyzer. I quoted the customer according to their requirements, and the customer also asked for some actual customer lists for installation. At noon, I was a bit busy and came to... The customer of the third testing company requires an orifice flow calibrator with a range of medium flow calibrator (70.00-140.0) L/min, After verifying, I recommended the equipment to the customer, quoted the price, and then the customer agent in Shanxi sent me a message saying that they needed a video of a portable oil and gas recovery detector, and arranged for technical support for after-sales. It was busy until mealtime, and so the morning passed.

In the afternoon, when I go to work, I usually arrange for shipment. Today's arrangement is to send a UV ozone analyzer purchased by Hunan Power Plant. After passing the inspection in the workshop, I compared the data myself and arranged for SF Express to ship it. Next, two portable open channel flow meters are the main products of our company, with stable testing data. We contacted Qingdao Metrology Institute to ship them and obtain calibration certificates. Around 4 pm in the afternoon, we started to follow up with potential customers before and after the Chinese New Year. Before we could complete the follow-up, when a customer visited, I put down my work and received the customer to the reception room. This customer is an environmental equipment supplier to the terminal. I recommended it to him. I took the customer to visit the factory area and explained the project categories to him. Making plans and so on, that's how my day's work ends at the end of the workday, Actually, the salesperson didn't finish work last night either. Normally, when they finished work at midnight and were cooking at home, they would have to turn off the fire and communicate and provide quotes to customers. Customer first, haha. I mainly enjoy this job, otherwise I wouldn't have done things so seriously and responsibly. I have been in the sales of instruments and equipment industry for seven or eight years, so I have many old customers. We not only have a relationship with customers and salespersons, but also with friends. Before the New Year, some instruments were quoted to customers, but when customers purchased them after the New Year, the company had already adjusted the price. However, I have already quoted the price to the customer, and I will definitely not increase it. That is too unprincipled. Even if I have no profit, I cannot let customers feel that we are not honest. This is my real instrument and equipment sales representative. Welcome new and old customers to support Qingdao Xinye Environmental Protection Technology Co., Ltd. Business Sales: Dan Limei

1、 Technical background and application

In order to implement the Environmental Protection Law and the Water Pollution Prevention and Control Law, protect the ecological environment, and safeguard human health, the Ministry of Ecology and Environment issued the "Technical Specifications for Installation of Online Monitoring Systems for Water Pollution Sources (CODCr, NH3-N, etc.)" and "Technical Specifications for Acceptance of Online Monitoring Systems for Water Pollution Sources (CODCr, NH3-N, etc.)" on December 24, 2019. In the "Installation Technical Specification", it is proposed that a flow monitoring unit is required in the composition of the online monitoring system. For the discharge units that need to measure the flow, standardized measuring weirs for open channels should be constructed

(Channel), and the construction of weir channels should be able to conduct comparison work of open channel flow meters. Triangular weirs, rectangular weirs, and Bacher channels are recommended. In the "Acceptance Technical Specification", specific requirements are proposed for the acceptance method of water pollution source flow monitoring units, which are divided into liquid level error comparison and flow error comparison, as follows:

(1) Liquid level error comparison: Use a portable open channel flow meter comparison device (liquid level measurement accuracy ≤ 0.1 mm) and an ultrasonic open channel flow meter to measure the liquid level value at the same water level observation section, conduct a comparison test, record the data pairs every 2 minutes for 6 consecutive times, calculate the error value Hi of each data pair, and select Hi as the liquid level comparison error of the flow meter.

(2) Flow Error Comparison: Use a portable open channel flow meter comparison device and an ultrasonic open channel flow meter to measure the instantaneous flow at the same water level observation section for comparison experiments. After the data is stable, start timing for 10 minutes. Read the cumulative flow F1 of the open channel flow comparison device and the cumulative flow F2 of the ultrasonic open channel flow meter during this period, and calculate the flow comparison error Δ F according to the formula.

According to the above requirements, it can be seen that a portable open channel flowmeter is needed for on-site acceptance. During the acceptance process, continuous statistics and recording of liquid level data and flow data are required. Within 12 minutes, 6 liquid level data of the online open channel flowmeter and 6 liquid level data of the portable sewage flowmeter need to be synchronously recorded

Within 10 minutes, synchronously record the cumulative flow data of two online open channel flow meters and two portable sewage flow meters. Moreover, because the sewage flow monitoring process is irreversible, once problems occur during the recording process, it is necessary to conduct a new comparison and acceptance, which brings difficulties to the on-site acceptance work in terms of time and space.

In response to the current lack of portable sewage flow meters in China that can easily and quickly complete the above acceptance tasks, our company has developed a portable open channel flow meter that meets the on-site acceptance requirements for open channel flow meters based on years of experience in environmental monitoring instrument research and development, combined with the technical specifications for installation of online monitoring systems for water pollution sources (CODCr, NH3-N, etc.), the technical specifications for acceptance of online monitoring systems for water pollution sources (CODCr, NH3-N, etc.), and the technical requirements and testing methods for ultrasonic open channel sewage flow meters in HJ 15-2019.

This portable open channel flow meter is mainly used for on-site technical parameter evaluation and acceptance of online open channel sewage flow meters, and can also be extended to flow measurement of open channel sewage discharge in enterprises.
