1. Introduction to the Babbitt measurement tank
The Babbitt measurement tank (also known as the Babbitt measurement tank) is an auxiliary equipment used for measuring the flow rate of sweet potatoes in pure channels. In the process of liquid flow, the waterway that flows in a non full pipe state is called an open channel. The application fields of open channel flow meters include urban water supply channels, cooling water intake and drainage channels for thermal power plants, sewage treatment inflow and discharge channels, industrial and mining enterprise wastewater discharge, as well as water conservancy engineering and agricultural irrigation channels.
2. National standard for Babbitt measuring tank
The current national standard for Babbitt measuring tank is JJG 711-90, which is applicable to open channel weir structures.
. 1. Core content of Babbitt measurement tank standard • Application scope: The standard covers open channel weir type Babbitt measurement tanks made of materials such as stainless steel and fiberglass, which need to be used in conjunction with ultrasonic open channel flow meters. • Technical advantages: It has the characteristics of non-contact measurement, strong adaptability to the site, and high measurement stability. The range ratio is up to 1:40, which is suitable for industrial sewage hail discharge monitoring and thousand ton level sewage treatment scenarios. • Typical application scenarios: inflow and outflow measurement of urban sewage treatment plants, flow monitoring of sewage outlets in chemical industrial parks, water allocation of 10000 acres of farmland irrigation areas.2. Extension of related standards. • GB/T Metal Material Babbitt Hardness Test: T

3. Does a sewage treatment plant have to use a Babbitt tank?
Generally, a Babbitt tank is used, which also facilitates online monitoring of water intake.
. Pipeline flow meters are not intuitive and are widely used.4. Gain knowledge! Calculation principle and construction points of Bacher trough, attached case
Calculation principle and construction points of Bacher trough, attached case Bacher trough calculation principle: Bacher trough is a monitoring device used for open channel flow, which accurately records flow data by controlling water flow and monitoring changes in water surface height. The calculation principle is based on the relationship between the geometric dimensions of the measuring weir and the water flow and liquid level in the channel. The larger the flow in the open channel, the higher the liquid level; The smaller the flow rate, the lower the liquid level. After installing the Bacher trough in the channel, the correspondence between the upstream water level and flow rate mainly depends on the geometric dimensions of the Bacher trough due to the smaller cross-sectional area of the trough compared to the channel. By measuring the liquid level of the water flow in the Bacher tank, and based on the corresponding water level flow relationship of the Bacher
