Orifice meter scale for measurement of saturated steam parameters when totalizer. especially for how to set

Abstract: the orifice meter scale parameter measuring the saturated steam totalizer. especially how to set up the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice meter is the standard orifice differential pressure transmitter with multiple parameters ( Or differential pressure transmitter, temperature transmitter and pressure transmitter) Form a complete set of high contrast range pressure flow device, can measure the rate of flow of gas, steam, liquid and gas. Widely used in stone. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the orifice meter scale parameter measuring the saturated steam totalizer. especially details how to set up the article. Orifice meter is the standard orifice differential pressure transmitter with multiple parameters ( Or differential pressure transmitter, temperature transmitter and pressure transmitter) Form a complete set of high contrast range pressure flow device, can measure the rate of flow of gas, steam, liquid and gas. Widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement. Orifice flowmeter is widely used in coal, chemical industry, transportation, construction, textile, food, medicine, agriculture, environmental protection and People's Daily life and so on each domain of national economy, is the development of industrial and agricultural production, save energy and improve the quality of our products and improve the economic benefit and the management level of the important tools in the national economy occupies an important position. In process automation instrument and apparatus, flow instrument has two functions: as a process automation control system of the testing instrument and measuring the amount of material quantity table. Orifice meter connected to signal lines, power cord; Open import, and export valves, import and export valve opening should be consistent; Balancing valve open three stainless steel valve group, slowly open the orifice to the high and low pressure valves, stay fluid through the flowmeter balancing valve can be closed after three stainless steel valve group. Can flow totalizer. especially for all kinds of liquid, steam, natural gas, the general gas flow parameters, such as measuring, accumulated calculation, alarm control, analog output, data acquisition and communication. Saturated steam: when the liquid in the airtight space limited evaporation, liquid molecules through liquid level into the space above, become a vapor molecules. Due to the vapor molecules in disorders of thermal motion, they collide with each other, and collision and vessel wall and liquid level, and the collision of liquid level, some molecules are attracted by the liquid molecules, and back to become liquid molecules in the liquid. Began to evaporate, the number of molecules into space than returns the number of molecules in the liquid, with the evaporation of the continued, space density increasing of vapor molecules, and returns the number of molecules of the fluid is also increasing. When the number of molecules per unit time into space and return equals the number of molecules in the liquid, the evaporation and condensation in a dynamic balance state, although the evaporation and condensation is still on, but the density of vapor molecules in space no longer increases, the state is called a saturated state. In saturation state of liquid called saturated liquid and its corresponding steam is saturated steam, but only at the beginning of zui wet saturated steam, for steam moisture is evaporated completely dry saturated steam. Orifice meter measuring saturated steam parameters when totalizer. especially for how to set? Saturated steam orifice plate test, density, temperature and pressure compensation requirements, according to the instantaneous flow rate and pressure automatic cycle 4 ~ 20 ma output. , supply and demand both sides agreed on user quantity when the flow rate is lower than 1 t/h steam press 1 t/h measurement, flow rate is higher than 40 more parts according to the 1 t/h. When the steam metering five times, without measuring. The user must provide the parameters of the examples are as follows: differential pressure transmitter, 4～20mA. ） Range of 60 kpa pressure transmitter ( 4～20mA. ） Range is 2 mpa pressure of 1. 3MPa（ Gage pressure) Temperature transmitter ( 4～20mA. ） Working temperature range of 300 ℃ for 195. 4 ℃ work intensity of 7. 1062 kg/m3 zui high flow rate of 50 t/h 1, the discharge coefficient K calculation: existing design data you do not need to calculate, or according to the following formula: F = K× （ dP× ρ ） Known F = 1/2, 50000, dP = 60 & rho; = 7. 1062 k = 2421. 452, instrument programming: functional menu prompt value function that FUN PSF 655 menu entry password PIN 2 main sensors for orifice, differential pressure transmitter without prescribing FC superheated steam temperature pressure compensation UNIT 4 0 instantaneous flow units: t/h, the cumulative flow for t.
