1. Composition of flowmeter
The flowmeter is mainly composed of five parts, which work together to achieve accurate measurement. 1. As the core of a flowmeter, sensors directly contact the fluid and convert flow information into physical signals. For example, an electromagnetic flowmeter is based on electromagnetic induction to measure the induced electromotive force and calculate the flow rate. The turbine flowmeter drives the turbine to rotate through fluid, reflecting the flow rate based on the rotational speed. two The converter is responsible for converting the sensor signal into a standard electrical signal (such as 4-20mA current or pulse signal or sparrow), and amplifying, filtering, and linearizing it to improve measurement stability and precision. The display unit intuitively displays instantaneous flow rate, cumulative data, temperature, pressure and other parameters. Some models support remote transmission for centralized monitoring and analysis of data. 4. The signal transmission system is connected to converters and display/control devices, and can be wired (cable) or wireless (Bluetooth, Wi Fi, GPRS) to meet different scene requirements. 5. The outer shell and accessories protect the internal components from environmental erosion; Attachments such as flanges, sealing gaskets, filters, etc. ensure stable installation and smooth operation, avoiding impurities from interfering with measurements.
2. Commonly used instrument characters and graphic symbols
Commonly used instrument characters and graphic symbols
1. Variable symbols Commonly used variable symbols are used to represent the physical quantities or states measured by the instrument, such as flow rate, pressure, temperat
III. Common graphic instrument symbols Graphic instrument symbols are used to visually represent the type and appearance of instruments, such as pressure gauges, flow meters, thermometers, etc. Here are some common graphical instrument symbols and their meanings: Circular with pointer instrument: usually represents a pressure gauge or similar instrument. Wave line graphic: represents a flow meter or similar instrument. Thermometer graphic: represents a thermometer or similar instrument. Rectangular graduated graphic: represents an electrical signal indicator or similar instrument. Valve graphics: represent various valves, such as globe valves, regulating valves, etc. (Image display: Common graphic instrument symbols, corresponding image links have been converted to markdown format)
IV. Tag introduction Tag numbers are usually composed of letters and numbers, used to uniquely identify instruments or equipment. The following are some common tags and their meanings: YAL: low alarm for leakage and teasing of news articles (Y refers to the sales status of news keys, A refers to alarm, L refers to low). FIQR: Flow indication, accumulation, recording (F refers to flow, I is indication, Q is
