1. What are the standard symbols for flow meters in PID diagrams?

In P&ID (Piping and Instrument Diagram), different types of flow meters have their own unique standard symbols, and common ones are as follows:

Sakura liquid, labeled with instrument tag number on the side, measures the flow rate of conductive liquid based on Faraday electromagnetic induction principle

4 Vortex flowmeter: The standard symbol is a circle with a vortex pattern, and the instrument tag number is marked on the side. The flow rate is calculated by detecting the vortex frequency generated by the fluid flowing through the blocking fluid.

3. What is FIQ flowmeter

1. FIQ stands for flow indicator instrument with cumulative quantity.

. F represents traffic, I represents indication, and Q represents accumulation.
2、 The measurement principle of a flowmeter is Faradays law of electromagnetic induction. The main components of the sensor are the measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. It is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including strong corrosive liquids such as acid, alkali, and cherry blossom salt. This product is widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceuticals, papermaking, as well as environmental protection, municipal management, and water conservancy construction.

4. Flow meter symbol

Flow meters use different identification symbols in different scenarios, mainly divided into two categories: graphic symbols and textual symbols.

. In engineering drawings or process diagrams, the i Icon of flow meter

ndustry standard for simulating the Hui symbol is usually represented by a circular base graphic for flow meters: an arrow pointing in the direction of fluid flow is added to the center of the circle, and functional codes are marked at the edges of the circle in the design of the Bi Wang section. For example, in industrial production drawings, "FT" represents a flow transmitter and "FRC" represents a flow controller with recording function. This labeling method complies with international standards such as IEC 61512. In physical calculation scenarios, flow is uniformly represented by the letter Q as a symbol. When it comes to specific flow types: volumetric flow is measured in m ³/s (cubic meters per second), while mass flow is measured in kg/s. This representation method is strictly defined by the International System of Units (SI) and is commonly used in scientific research papers and equipment technical parameter tables. In industrial automation control system drawings, flow meters are identified by functional letter combinations: for example, flow detection elements are labeled as FE (flow sensor), flow alarms use FAL (low flow alarm), and flow control valves use FCV identification. These symbols are compiled according to the ISA-5.1 instrument symbol standard, which directly affects equipment selection and system integration.

5. How to represent mass flowmeter in CAD

Mass flowmeter in CAD: The volume of the fluid in the mass flowmeter is a function of the fluid temperature and pressure, and is a dependent variable, while the mass of the fluid is a quantity that does not change with time, space temperature, and pressure.
