The application of intelligent 3051 differential pressure transmitter is more extensive, today we will sort out the main applications of intelligent 3051 differential pressure transmitter, and give examples of how the intelligent 3051 differential pressure transmitter is used. Measuring flow: Intelligent 3051 differential pressure transmitter is used in flow measurement and metering, which is simple and reliable and easy to use. Application example: Flow measurement of crystallizer cooling water detection systems in metallurgical plants. A throttling device is installed in the pipe through which the medium passes, and when the medium passes, a differential pressure is generated before and after it, and the size of the differential pressure is related to the flow rate of the medium passing through. In this way, the flow rate is measured by means of a throttle device (orifice plate, nozzle or venturi) in combination with the intelligent 3051 differential pressure transmitter. Measuring liquid level: another typical application of differential pressure transmitter is to detect liquid level, the measured liquid level equipment is diverse, measurement methods are different, but the measurement principle is to use the static pressure of the liquid, in the known liquid column height h and liquid density ρ, then △P = hρ, differential pressure and liquid level in a linear relationship. Therefore, the core of the calculation is to find out the static pressure detected by the high and low pressure measuring chambers of the differential pressure transmitter, and compare the two to determine whether migration is required, whether it is positive migration or negative migration, and what is the migration amount during migration. Application example: Level measurement of closed tanks in water treatment plants. For closed containers, the pressure inside the tank may change from positive pressure to vacuum when the process fluid fills or empties the tank due to the internal isolation from the atmosphere. This change in the pressure in the tank directly affects the level being measured unless compensated. This can be done by connecting the low-side piping of the Smart 3051 differential pressure transmitter to the top of the tank. Therefore, when measuring the level of a closed tank, the intelligent 3051 differential pressure transmitter must be used. Measuring weight: from the principle of measuring the liquid level of the differential pressure transmitter, it is known that the output of the differential pressure transmitter is proportional to the liquid level when the severity is equal to the constant; Similarly, when the liquid level is equal to the constant, the output of the differential pressure transmitter is proportional to the heavy degree, so the differential pressure transmitter can be used to measure the heaviness. Measure micro positive pressure or micro negative pressure: The differential pressure transmitter has two pressure taking chambers, when the negative pressure chamber is connected to the atmosphere, the positive pressure chamber is connected to the pressure point, which can be used for pressure measurement, while the positive pressure chamber is connected to the atmosphere, and the negative pressure chamber is connected to the pressure point, which can be used for negative pressure measurement. Application example: the three-effect process of the printing and dyeing factory, often need to measure the specific gravity of the liquid in the process, the traditional method is sampling method and blowing method, but more devices are required, the sampling cycle is long, especially for viscous and high-temperature media are more difficult to handle. The intelligent 3051 differential pressure transmitter allows the weight of the process medium to be measured at any time without sampling. Application example: intelligent 3051 differential pressure transmitter is used to measure the boiler jealous micro negative pressure, the boiler due to the needs of fuel table combustion, the furnace pressure is required to be controlled within a range of 50Pa, this micro negative pressure can be measured with the intelligent 3051 differential pressure transmitter. Measurement of micro-positive pressure in the heating furnace. In addition to considering the reasonable combustion factors of the fuel, the heating furnace also needs to protect the under-oxygen state of the combustion process, because the oxygen enrichment is easy to cause the increase of oxide scale on the surface of the heated part, resulting in loss, so it is generally controlled in the state of micro-positive pressure. The intelligent 3051 differential pressure transmitter can be used for micro-positive pressure measurement in heating furnaces.
