The Reason This “Traditional” Level Instrument Has Not Been Replaced In modern process industries, radar level transmitters are often considered one of the most advanced technologies for liquid level measurement. With advantages such as non-contact measurement, high accuracy, and low maintenance requirements, radar technology has become widely used in industries including oil & gas, chemical […]
Introduction Selecting the right flowmeter is essential for accurate process measurement, efficient operation, and long-term reliability in industrial systems. However, choosing a flowmeter is not simply a matter of matching the meter size to the pipeline diameter. Different flow measurement technologies have different operating principles, application limitations, and installation requirements. A flowmeter that performs well

Many chemical projects reach the final stage and only then begin preparing acceptance documents, arranging inspections, and organizing compliance reviews. However, problems discovered during acceptance are often not new. In many cases, they have already existed throughout the earlier stages of engineering design, procurement, construction, commissioning, and change management. For example: Safety systems may already

A vortex flow meter that suddenly starts displaying unstable readings can create serious problems in industrial operations. Flow values may jump unexpectedly, oscillate during otherwise steady operation, or even indicate flow when the pipeline is supposed to be shut down. The immediate reaction is often to suspect a faulty sensor or transmitter. However, unstable vortex
If you work with pressure transmitters, pressure gauges, control valves, or valve positioners, you may have encountered this situation during calibration: You gradually increase the input to a certain value and record the instrument output. Then you approach exactly the same input value from the decreasing direction — but the instrument gives you a slightly

A turbine flow meter showing a fluctuating or unstable output signal is a common problem in industrial applications. The reading may jump up and down even when the process appears stable. Is it electrical interference? Air in the pipeline? Improper installation? Or a problem with the turbine rotor? Instead of checking components randomly, follow this

Over the past few years, 80 GHz radar level transmitters have become increasingly popular in industrial level measurement. Manufacturers frequently highlight their narrow beam angles, excellent signal focusing, high measurement accuracy, and ability to operate in challenging environments. As a result, some engineers automatically select 80 GHz radar for new projects, assuming that a higher

How Pressure and Temperature Compensation Prevents Hidden Errors in Industrial Steam Measurement Imagine this situation: A factory’s monthly steam consumption report shows significantly more steam than the downstream production departments believe they have used. The maintenance team inspects the steam pipelines. No obvious leaks are found. The vortex flowmeter passes its basic diagnostic checks. Its

A thermocouple is one of the most widely used temperature sensors in industrial applications. However, after long-term operation under high temperature, vibration, corrosion, or mechanical stress, thermocouples may fail and cause inaccurate temperature readings. This article introduces several practical methods to quickly check whether a thermocouple is working properly in the field. 1. Visual Inspection
Consider a factory using superheated steam for industrial heating. A vortex flow meter was originally configured for the following operating conditions: Steam pressure: 6 bar(g) Steam temperature: 200°C Fluid: Superheated steam Measurement requirement: Mass flow rate in kg/h The system operated normally until a process adjustment reduced the steam pressure to 5 bar(g), while the
