Seven Key Points for Electromagnetic Flowmeter Selection: Accuracy and Functionality: Choose the appropriate accuracy level based on measurement needs, and consider necessary functions such as bidirectional measurement or alarms. Flow Rate and Diameter: Determine the fluid’s flow rate range and select the proper sensor diameter to ensure measurement accuracy. Fluid Properties: Consider the fluid’s conductivity, […]

As shown in Figure 1, the upstream pressure tapping point is located 25.4 mm from the upstream face of the orifice plate, and the downstream pressure tapping point is also located 25.4 mm from the downstream face of the orifice plate. When using flange pressure tapping, the pressure tapping flange is included as part of

Instrumentation and electrical systems can be differentiated from the following aspects: 1. Definitions and Functions Instrumentation: Definition: Refers to devices or systems used to measure, display, control, and record physical quantities such as temperature, pressure, flow, and liquid levels. Function: Primarily focused on the precise detection and monitoring of various physical quantities to provide accurate

Introduction Process detection and control instruments play a crucial role in ensuring production safety and smooth operation. Whether an instrument is functioning properly is directly related to the continuity and safety of chemical production. Therefore, maintaining and servicing instruments is essential. Instrument Maintenance Daily maintenance of instruments reflects the preventive ideology of Total Quality Management

1. Basic knowledge of instruments Instruments are key components in industrial automation systems, and are mainly used to measure, record, control and adjust various physical quantities, such as temperature, pressure, flow, liquid level, etc. The basic function of instruments is to achieve signal conversion, that is, to convert the measured physical quantity into a standard

After being in use for a period of time, electromagnetic flowmeters may suddenly become inaccurate, which undoubtedly causes significant inconvenience to industrial production. This article will explore the reasons why electromagnetic flowmeters become inaccurate after some time and offer solutions to these problems. First, let’s analyze the possible causes: Sensor Contamination: During operation, the sensor

Flammable gases can be classified as either single flammable gases or mixed flammable gases, both of which have flammable and explosive properties. The explosion limit refers to the concentration range within which a flammable gas, when mixed with an oxidizing gas, will explode under standard testing conditions. Oxidizing gases can include air, oxygen, or other
