What is the Working Principle Behind DP Transmitters?
I often encounter confusion about how differential pressure transmitters actually measure flow. A DP transmitter works by measuring the pressure difference between two points in a flow system, converting this differential pressure into an electronic signal for flow rate calculation. DP Transmitter Basic Components Let me break down the complexities of DP measurement technology. How […]
What Quality Control Standards Should a Transit Time Ultrasonic Flow Meter Meet?
Last month, a client lost thousands in revenue due to an uncertified flow meter failing calibration checks. Quality standards aren’t just paperwork – they’re essential for reliable measurement. Transit time ultrasonic flow meters must meet international standards like ISO 17025 for calibration, OIML R49 for water metering, and hazardous area certifications when applicable. They should […]

Transit time ultrasonic flow meter installation requires proper tool selection, location planning, careful mounting, and thorough calibration. Following manufacturer guidelines and best practices ensures optimal performance. Installation Overview Diagram Performance Flow Rate ±0.03m/s~±12m/s […]
Understanding Transit Time Ultrasonic Flow Meters in High Temperature Applications: What Should You Know?
Last year, a power plant lost significant revenue when their steam flow measurements became unreliable. The culprit? They didn’t account for high-temperature effects on their ultrasonic flow meter installation. Transit time ultrasonic flow meters in high-temperature applications (above 150°C) require special considerations for material selection, temperature compensation, and installation methods. Proper setup can maintain accuracy […]
How Does a Transit-Time Ultrasonic Flow Meter Work?
At a recent chemical plant installation, we faced significant measurement errors. After investigation, I discovered the root cause wasn’t equipment failure – it was a fundamental misunderstanding of how transit-time technology works. A transit-time ultrasonic flow meter measures flow by calculating the difference in time it takes for ultrasonic signals to travel upstream versus downstream […]
