Project Background Vortex flowmeters are a cornerstone of accurate flow measurement across the chemical, petrochemical, water treatment and power generation industries. However, even a well-engineered vortex flowmeter can deliver unreliable readings when it is exposed to adverse installation ...

Project Background Accurate measurement of compressed air is essential for energy management, leak detection and cost control in modern production facilities. When an industrial client deployed an E+H mass flowmeter to monitor compressed air consumption, the initial readings were unstable and ...

Customer Background The turbine-generator is the heart of a thermal power plant, and mechanical quantity instruments are the electrocardiogram that watches it beat. In the thermal instrumentation of a 600 MW-class power plant we support, the Turbine Supervisory Instrumentation (TSI) system ...

Customer Background A thermal power plant instrumentation team operates hundreds of pneumatically actuated control valves in boiler, turbine and auxiliary systems, fitted with positioners of different generations and brands, including SIPART PS2, Fisher DVC2000 / DVC6200, ABB TZID-C and YTC YT-2500 ...

Customer Background Control valves are the final control elements of every process loop. In thermal power plants, petrochemical and metallurgy plants, smart valve positioners receive the 4-20 mA signal from the DCS and precisely position the valve while providing travel feedback and self-diagnosis. ...

Reliable Furnace Negative Pressure Measurement for Thermal Power Plant Boilers In thermal power plant boiler operation, furnace negative pressure (furnace draft) is one of the most critical safety parameters of the air-flue gas system. The furnace is normally kept under a slight negative pressure of ...

1. The output voltage of the 3300XL series proximity sensor system has a ( ) relationship with the distance between the probe and the surface of the measured conductor. A. Square root B. 20KPa C. Linear D. Parabolic 2. Which of the following is NOT a function of the 3500/22M card? ( ) A. Alarm ...

Comprehensive Analysis of Core Parameters of Water Quality Analyzers: Understanding the Significance Behind Indicators such as pH, ORP, and Conductivity Water quality safety is a critical issue for environmental protection and human health. Water quality analyzers provide a scientific basis for ...

A. Core Selection Parameters 1. Measurement Type Gauge Pressure: For conventional industrial scenarios (referenced to atmospheric pressure). Absolute Pressure: For vacuum or sealed systems (referenced to vacuum zero point). Differential Pressure: For flow and liquid level monitoring (e.g., orifice ...

I. Working Principles (Two Mainstream Types) 1. Coriolis Mass Flow Meter (Most Commonly Used, Compatible with Liquid/Gas/Slurry) Core Principle: Coriolis effect Operating Process: The measuring tube is driven to vibrate at its natural frequency. When fluid flows through, a Coriolis force proportiona...

The performance indicators of on-line analytical instruments cover a broad range of meanings, but can generally be divided into two categories. One category of performance indicators is related to the working range and operating conditions of the instrument. The working range mainly refers to the ...

Applicable to: 3300XL series probes (8/11/14mm) + 330180 series proximitors, paired with 3500 vibration/displacement monitoring cards. The process is divided into 5 steps from simple to precise: visual preliminary inspection → power-off electrical testing → power-on voltage verification → TK-3E ...
