1. What is the standard English abbreviation for chemical process instruments?

There is no unified general standard English abbreviation for chemical process instruments, and different types of instruments have their own commonly used standard English abbreviations. The following are the common types and corresponding abbreviations.

1. Temperature instrument - Thermocouple: TC (Thermocouple) - Thermistor: RTD (Resistance Temperature Detector) 2. Pressure instrument - Pressure transmitter: PT (Pressure Transmitter) - Differential pressure transmitter: DPT (Differential Pressure Transmitter) 3. Flow instrument - General flow transmitter: FT (Flow Transmitter, often used with orifice plates and other throttling devices) - Electromagnetic flowmeter: EMF (Electromagnetic Flowmeter) 4. Level Instrument - Level Transmitter: LT (Level Transmitter) - Radar Level Gauge: RLG (Radar Level Gauge)

Orifice Meter is also known as differential pressure flowmeter is determined by a test piece (cutting pieces) and the second device (differential pressure transmitter and flow indicator), is widely used in gas, steam and liquid flow measurements. It has the characteristics of simple structure, easy maintenance, stable performance, and reliable use. Has a simple structure, easy maintenance, stable performance, reliable and so on. Detailed introduction:

1. Overview Orifice flowmeter, also known as differential pressure flowmeter, is composed of a primary detection element (throttling element) and a secondary device (differential pressure transmitter and flow display instrument), widely used for flow measurement of gases, vap

ors, and liquids. Details: First, an overview of orifice flow meter is also known as differential pressure flowmeter is determined by a test piece (cutting pieces) and the second device (differential pressure transmitter and flow indicator), is widely used in gas , steam and liquid flow measurement. It has the characteristics of simple structure, easy maintenance, stable performance, and reliable use. Has a simple structure, easy maintenance, stable performance, reliable and so on. The orifice plate throttling device is a standard throttling component that can be produced directly in accordance with national standards without calibration. 1. National standard GB2624-81

2. Working principle: The fluid filled in the pipeline flows through the throttling device inside the pipeline, causing local contraction near the throttling element, increasing the flow velocity, and creating a static pressure difference on both sides upstream and downstream. 2, the working principle of fluid flowing through the pipeline is full of pipe
