V cone bimetallic thermometer application in farmland irrigation

With the development of science and technology, more and more new technologies have been widely used in petroleum, chemical, natural gas bimetallic thermometer, long distance pipeline, thermal pipe network, metallurgy, electric power, water treatment, pharmaceutical, paper making, food, aerospace and other industries in production. V cone bimetallic thermometer is a typical representative of many novel features are popular with more and more people. Become the darling of the bimetallic thermometer industry, its comprehensive measurement, no doubt, be applied to various fields, for everybody below simply introduces the application of it in the farmland irrigation: M4X magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

V taper bimetallic thermometer diving used to measure open channel or pipe culvert with free surface free flow of traffic. Sensor at the bottom of the river closure of open channel baffle, work under water for a long time. Irrigation and water conservancy of constructing is the important measure of agricultural development in our country. Without irrigation water conservancy construction, especially correctly grasp the method of flow measurement in the irrigation system is crucial. At present there are mainly two kinds of methods, namely the speed - area method and hydraulic method, each method has its unique flow sensor ( Detection) Part.

speed - area to measure flow rate is multiplied by the average velocity by water channel cross-sectional area, the water flow rate through the wedge bimetallic thermometer at some particular point is measured. Use this law to measure flow rate and generally there are three different ways: one is the velocity distribution law; The second is 0. 6 h method ( H for the water surface to the end of channel distance) ； Three is 0. 2H～0. 8 h method. Velocity distribution law is measuring several points between water surface and the bottom of the canal, and determined by the measuring point on a vertical surface speed curve, the speed curve defined area is divided by the depth, can calculate the average speed; 0. 6 h to measure the water below 0. 6 h deep single point velocity, and assumes that the value is the average of all the speed; 0. 2H～0. 8 h method of measurement is 0 under surface water. 2 h and 0. The flow rate of the depth of 8 h 2 o 'clock, this is the average of the two readings can estimate for average velocity value.

is a cone in the center of the pipe installation to throttle, by measuring the differential pressure is measured before and after of the pyramidal flow. The geometry of a cone compared with the traditional throttling device has many advantages, so it is a new generation of throttling device. V-shaped cone bimetallic thermometer with traditional differential pressure type bimetal thermometer, by three valve group, pressure pipe, composed of differential pressure transmitter, flow totalizer. especially standard volume flow measurement system. For a compressible medium, such as gas and steam can realize temperature and pressure compensation, mass flow measurement system. Bimetallic thermometer with its superior performance suitable for different working environment, especially in the industrial production of large flow, low pressure, high humidity gas and coke oven gas, natural gas and other dirty fluid measurement.

in any one particular average velocity measurement area calculation. Along the channels of the entire width of the depth and the number of a single vertical plane measurement points are different.
