1. The flowmeter symbol

is represented by S. A flowmeter, also known as a flow meter, measures the instantaneous flow rate and cumulative volume of a liquid, and can also be used for quantitative control of the liquid. It has the characteristics of high precision, long lifespan, easy operation and maintenance. It is mainly used in industrial production, energy measurement, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, Rivers and Lakes and other leading areas. The working principle of electromagnetic flowmeter is based on Faradays law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faradays test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrodes through non-conductive lining (rubber, Teflon, etc.)

2. What is the meaning of the "r" symbol in industrial flow meters

The "R" symbol in industrial flow meters has four common meanings depending on the application scenario

1. Connection method is identified in the model code of vortex flow meters and other models, where "R" represents the threaded connection method. For example, model "1R" refers to a vortex flowmeter with a diameter of 1 inch and threaded connection. In the application of inflow flow meters, R is the flow area factor (also known as the cavity coefficient or pipe coe

4. In the metal tube rotor flowmeter, the "R" series car train code indicates a specific liquid contact material: - R0: 0Cr18Ni2Mo2Ti stainless steel - R1:1Cr18Ni9Ti stainless steel. The specific meaning needs to be confirmed in conjunction with the flowmeter model nameplate, technical manual, or application scenario.

3. How is a mass flow meter represented in a process flow diagram? The symbol of a mass flowmeter in a process flow diagram represents that the volume of the fluid is a function of fluid temperature and pressure, and is a dependent variable, while the mass of the fluid is a quantity that does not change with time, spatial temperature, or pressure. As mentioned earlier, commonly used flow meters such as orifice flow meters, turbine flow meters, vortex street flow meters, electromagnetic flow meters, rotor flow meters, ultrasonic flow meters, and elliptical gear flow meters measure the volume flow rate of the fluid. The fluid volume involved in scientific research, production process control, quality management, economic accounting, and trade handover activities is generally quality. The use of the above-mentioned flowmeter to measure only the volumetric flow rate of the fluid often cannot meet peoples requirements, and it is usually n
