Selection skills of flow meter (flow meter)

Abstract: The selection skills information of flow meter (flow meter) is provided by excellent flow meter and flow meter manufacturers. Selection skills of flow meters (flow meters): The selection of flow meters (flow meters) often plays a very important role in the successful use of the meters. Instrument selection. For more flow meter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the selection skills articles of flow meters (flow meters). Selection skills of flow meters (flow meters): The selection of flow meters (flow meters) often plays a very important role in the successful use of the meters. Difficulty in instrument selection. There is no one perfect flowmeter. All kinds of meters have their own characteristics. The purpose of model selection is to choose the most suitable flowmeter and meter among many varieties. (1) General selection of flow meters (flow meters): It can be considered from five aspects, which are the performance of flow meters, fluid characteristics, installation conditions, environmental conditions and economic factors. The detailed factors of the five aspects are as follows: 1. In terms of instrument performance: accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss, etc.; 2. In terms of fluid characteristics: temperature, pressure, Density, viscosity, chemical corrosion, abrasiveness, scaling, miscibility, phase transition, electrical conductivity, sound velocity, thermal conductivity, specific heat capacity, isentropic index; 3. Installation conditions: pipeline arrangement direction, flow direction, upstream and downstream sides of the detection piece Length of straight pipe section, pipe diameter, maintenance space, power supply, grounding, auxiliary equipment (filters, air eliminator), installation, etc.; 4. Environmental conditions: ambient temperature, humidity, electromagnetic interference, safety, explosion-proof, pipeline vibration, etc. 5. Economic factors: instrument purchase, installation, operation, calibration, maintenance, instrument service life, spare parts, etc. (2) The steps for the selection of flowmeter instruments are as follows: 1. According to the type of fluid and five factors to consider, select the available meter types (there must be several types for selection); 2. Provide data and price information for the primary type 3. Use the elimination method to gradually focus on 1 or 2 types, and repeatedly compare and analyze the five factors to finally determine the pre-selection target. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Selection Skills for Flow Meters (Flow Meters)'
