Differences Between Insert-Type and Clamp-On PT1000 Temperature Sensors
PT1000 temperature sensors are widely used in industrial automation, HVAC, chemical processing and fluid monitoring due to their high precision, good stability, and consistent linearity. Following the IEC 60751 standard, PT1000 provides higher resistance and better signal sensitivity compared wi...Read more -
Why Does the Reynolds Number Affect Flow Measurement?
The Reynolds number (Re) is one of the most important dimensionless parameters in fluid mechanics. It helps describe the relationship between inertial forces and viscous forces in a flowing fluid and is commonly used to determine whether the flow is laminar, transitional, or turbulent. For ultras...Read more -
Why Does Pipe Lining Affect Clamp-on Ultrasonic Flow Measurement?
Pipe lining is an important factor to consider when installing a clamp-on ultrasonic flow meter. Although the transducers are mounted on the outside of the pipe, the ultrasonic signal must pass through the pipe wall and, in many cases, the internal lining before reaching the liquid. Therefore, th...Read more -
Why Does an Ultrasonic Flow Meter Need Straight Pipe Runs?
Proper installation is essential for achieving stable and accurate measurements with an ultrasonic flow meter. One of the most important installation requirements is the straight pipe length before and after the measurement point. As a general installation guideline, an ultrasonic flow meter shou...Read more -
What Does Signal Strength Really Mean in an Ultrasonic Flow Meter?
For a clamp-on transit-time ultrasonic flow meter, signal strength is one of the most useful diagnostic parameters. However, there is a common misunderstanding: A high signal strength does not necessarily mean high measurement accuracy, and a low signal strength does not necessarily mean that the...Read more -
Why Does an Ultrasonic Flow Meter Experience Zero-Point Drift?
For an ultrasonic flow meter, zero-point drift refers to a situation where the meter indicates a small flow rate even when the pipe is supposed to be at zero flow. This phenomenon is particularly important for transit-time ultrasonic flow meters, because the flow rate is calculated from the diffe...Read more -

Can the DOF6000 Doppler partially filled pipe flowmeter be used in a full-pipe application?
Yes. The DOF6000 Doppler flowmeter is not limited to partially filled pipes. It can also be used in certain full-pipe applications, especially where a conventional clamp-on transit-time flow meter is not the most suitable solution. The DOF6000 flowmeter measures flow based on flow velocity and w...Read more -
For clamp on ultrasonic flowmeter, what should I do if the pipe is partially full?
A standard clamp-on ultrasonic flow meter is generally designed for full-pipe applications. If the pipe is partially full, the ultrasonic signal may not travel correctly through the liquid, which can affect measurement accuracy and stability. If possible, consider modifying the installation or p...Read more
