Xi'an QW-RSL-type thermal gas mass flow meter

Product Main Features * Direct measurement of the quality of the pipe fluid flow measurement accuracy, repeatability, and can be in a wide measuring range, directly measuring fluid mass flow *. Mass flow measurement accuracy measurement of the flow meter accuracy of 0.2. * stable and reliable measurement of fluid inside the tube without obstacles and moving parts, thus high reliability, long life. * In addition to wide adaptation of the fluid medium is generally uniform fluid viscosity, it can also measure high viscosity fluids ( honey, oil slurry, etc.); fluid parameters can be measured not only single solution, it can also measure multiphase flow; whether the medium is laminar or turbulent flow, do not affect the measurement accuracy. * Wide range of applications used in petrochemical, chemical, metallurgical, pharmaceutical, paper, food, energy and environmental protection industries, the detection control and custody transfer metering process and other occasions, access to a wide range of applications, * more real-time online monitoring and control functions in addition to the mass flow rate, but also directly measure the fluid density and temperature. Intelligent flow transmitter that provides a variety of parameters of the display and control functions, is a set of functions as one of the flow measurement and control instruments. * Scalability good company based on user needs, designs and manufactures mass flow particular type and special features; also for remote monitoring operation. Batching and batch main purpose and scope TY-RSL-type thermal gas mass flow meter products in the following areas of various feeds, measurement and control processes in material flow, fast-changing density measurement, as well as products quality control, etc., can play a very effective role. TY-RSL-type thermal gas mass flow meter is mainly used to measure the mass flow rate and the total amount of the medium, density, at the same time, it can measure the volumetric flow rate and total, medium temperature, moisture, alcohol alcohol, mixed compared uniform concentration of two liquids, process flow ratio of raw materials and the like. It is mainly applied to the following sectors: (1) the oil industry, such as the measurement of crude oil production, water content, measure well production, transportation of crude oil metering (2) chemical industry (3) the food industry (4) pharmaceutical manufacturing industries, such as liquid measure the production of pharmaceuticals (5) the paper industry, such as the measurement of pulp (6) textile industry (7) Measurement of energy delivery, such as liquefied petroleum gas metering (8) the environmental protection industry, such as wastewater treatment; desulfurization slurry density measurement Product main functions: ( 1), the measurement function can directly measure the instantaneous mass flow rate of the liquid medium, the cumulative total mass, volume flow rate, total volume, temperature, density, two-component liquid concentration and the like. You can display, output, storage and remote transmission; modify the meter parameters. (2), the current output of the product has a current signal output, current output is 4mA ~ 20mA, to meet the needs of industrial instrumentation control. (3), this product has a frequency output frequency signal output, frequency output is 0KHz ~ 10KHz, can meet the needs of industrial instrumentation control. (4), batch control Batch Control relay contact capacity: 24V / 0.1A, contact form is normally open (when the user ordering instructions can be changed to normally closed), this function can meet flow batch control industrial equipment. (5) Communication features of this product data communication capabilities available through RS-485 communication, complete data communication with the computer, enabling control of the computer network. (6), safety explosion of the mass flow meter has been double-proof credentials. Structural principle mechanism TY-RSL thermal gas mass flow meter is a double bend structure, the measurement principle is: the wall will generate a force of the fluid flow within the rotation of the tube, it is the Coriolis research turbine in 1832 When found, it referred to the Coriolis force. Coriolis mass flowmeter based in internal vibration sensor has two parallel tubes, middle mounted drive coil, both sides with pick-up coil, the excitation voltage is applied to the transmitter provides the driving coil, vibrating tube reciprocating cycle vibration, industrial process fluid medium flowing through the sensor vibrating tube, Coriolis force is generated in the vibration control effect, so the two vibrating tube vibration, vibration control mounted on both sides of the pick-up coil to generate a phase two different signals, the difference between these two fluid mass flowing through the sensor signals is proportional to the flow rate. Computer construed accordingly calculated mass flow through the vibrating tube. When the density of the medium flowing through the different sensors, the vibration frequency of the different vibration control, which can be calculated by medium density. Vibration sensor mounted on the tube platinum resistance temperature of the medium can be measured indirectly. Part of the product: The product consists of two parts by a sensor (one meter) and transmitter (secondary meter). Sensor is a mechanical part of the mass flow meter, with internal vibrator, displacement sensors, and temperature sensors. Transmitter is part of the instrument display, but also the electrical part of the instrument. It is equipped with an internal power supply, analog circuitry, digital circuitry, and display output, etc., the basic functions are: to receive and process the electrical signal of the sensor, processed directly mass flow, volume flow, temperature and density, can be displayed, output, storage and remote transmission; modify the meter parameters. Transmitters are equipped with an internal barrier, from the explosion isolation protection. Composite flowmeter sensor is intrinsically safe transmitter is flameproof, sensors and transmitters can operate in an explosive atmosphere, can be placed in the danger zone. Sensor intrinsically safe flowmeter is intrinsically safe, you can use an explosive atmosphere, the transmitter can work in a safe environment. Specifications: Our products Model TY-RSL series thermal gas mass flow meter, according to the nominal pipe diameter can be divided into: DN6, DN10, DN15, DN25, DN40, DN50, DN80, DN100 (in mm) eight kinds of specifications.
