Pay attention to the following problems when applying the open channel panel flowmeter:

1) As the places of ultrasonic sensor for equipment waste water are all places with poor analogy, the server of instrument and equipment shall be installed in the room, with full-time personnel as the caretaker, and the route and sensor shall be guarded on time.

2) The instrument and equipment shall be calibrated on time.

The following problems should be paid attention to when using the open channel ultrasonic flowmeter:

(1) Selection

(2) Open channel ultrasonic flowmeter. Due to the wide common limitation of liquid purging flowmeter (pipe diameter from 12mm to 5m, and even larger), Secco has adopted several ultrasonic liquid flowmeter to measure circulating water, with pipe diameter from DN80 to DN1000. The instrument panel is selected with sound guide professional skills, which can accept various preconditions of extreme processing technology (high temperature resistance limitation: - 200 ~ 600 ℃; compression resistance limitation: it can be leveled with the processing flange) to measure the flow. Open channel ultrasonic flowmeter is a kind of flowmeter widely used in wastewater treatment plant. There is a clear relationship between the liquid flow in the open channel and the liquid level instrument at a certain point on the tank. For a stainless steel tank with a certain appearance design, the flow can be carried out only when the liquid level instrument is precisely measured.

1) In order to ensure that the waste water flowing through the flow tank at the maintenance port is free of dirt, it is necessary to modify the filter screen near the upstream and downstream of the flow tank of the intelligent target flowmeter. Problems to be paid attention to in ultrasonic flowmeter equipment and application. Because ultrasonic is related to the shortcomings of electronic devices detection instrument itself, such as vulnerable to temperature, radiation sources and other hazards, if the equipment and application is not appropriate, it will not be optimistic about its measurement and application life. Therefore, the following problems should be paid attention to when using the open channel ultrasonic flowmeter:

2) In order to ensure that the sewage flowing through the flow channel at the manhole is stable and free of wavy lines, a static deep water well can be set at the side of the flow channel to communicate with the channel. The nominal diameter of the well is greater than or equal to 90mm, the minimum position of the well shall be 150 mm less than the driving channel, the total width of the straight section of the driving channel shall be greater than or equal to 10 times the total width of the weir River, and the dirty water line shall be less than the minimum water line of the weir plate.

3) The sending surface of the sensor camera hair shall be parallel to the liquid level, and the distance between the lower inner hole of the sensor and the liquid level meter shall be greater than or equal to 0.4m

4) There should be no strong light, magnetic field and other radioactive substances around the sensor.

5) The ultrasonic sensor shall be protected from rain and snow.

(2) Open channel ultrasonic flowmeter equipment and problems to be noticed in application. Because ultrasonic is related to the shortcomings of electronic devices detection instrument itself, such as vulnerable to temperature, radiation sources and other hazards, if the equipment and application is not appropriate, it will not be optimistic about its measurement and application life. Therefore, the following problems should be paid attention to when using the open channel ultrasonic flowmeter:
