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. What is a Bacher groove? The prototype of the Parshall flume is the Venturi flume, which was experimented with by VM. Cone in Colorado, USA in 1915. In 1922, F.L. Marshall made a fundamental change to this and created the now widely used Bachel groove. Afterwards, they engaged in multiple battles and repeated hydraulic experiments, creating various measuring tanks ranging in size from 1 inch to 50 inches. The name Bacher Trough was given by the American Society of Civil Engineers in 1929. Afterwards, many countries such as the United Kingdom, Switzerland, Italy, India, Argentina, etc. also proposed various types of design schemes for Venturi sinks and conducted experiments, but the Bachel sink is still the most popular sink in Venturi sinks. 3. What is the measurement principle of the Babbitt flowmeter
The Babbitt slot flowmeter is the most commonly used throat type measuring slot, with an accuracy of 95% to 98%.
. Measure the upstream water level H1 of the Babbitt tank through a differential pressure level gauge, monitor the drain
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 ra
