How Do Open Channel Flow Meters Serve Modern Water Management?
An open channel flow meter is a specialized flow measurement device designed to calculate the volumetric flow rate of liquids flowing in open or partially closed channels, such as unpressurized pipelines, drainage ditches, canals, and natural waterways. Unlike closed-pipe flow meters that rely o...Read more -
Understanding Float Flowmeters (Rotameters): Principle, Structure, Features and Applications
A float flowmeter, also widely known as a rotameter or variable area flowmeter, is one of the most traditional, practical, and cost-effective flow measurement instruments in industrial fluid control systems. Designed for measuring the volumetric flow rate of liquids, gases, and vapors, it has ma...Read more -
How to Install an Ultrasonic Open Channel Flow Meter for Accurate Measurement
Installation Guide for Wastewater, Sewage and Partially Filled Pipe Flow Measurement Correct installation is one of the most important factors affecting open-channel flow measurement. For an ultrasonic open-channel flow meter, the sensor needs a suitable hydraulic environment to obtain stable ve...Read more -
Open Channel Flow Measurement for Wastewater, Sewage and Partially Filled Pipes
Wastewater and sewage flow measurement can be challenging because the liquid conditions are often different from those of clean water. The flow may contain suspended solids, sludge, air bubbles and other contaminants. In addition, many wastewater pipelines operate as partially filled pipes rath...Read more -
Open Channel Flow Meter Troubleshooting: Common Problems and Solutions
An open-channel flow meter measures flow under changing hydraulic conditions, so measurement problems can have several possible causes. When a customer reports unstable, zero or incorrect flow readings, it is important to check the installation location, water level, sensor condition, channel pa...Read more -
Open Channel Flow Meter Selection Guide: How to Choose the Right Flow Measurement Solution
Selecting a flow meter for an open channel or partially filled pipe is different from selecting a conventional full-pipe flow meter. In a full pipeline, the pipe is completely filled with liquid and the flow rate can be calculated based on the pipe cross-section and flow velocity. In an open cha...Read more -
Advantages of Multi‑Path Ultrasonic Flow Meters for Complex Industrial Measurement
Single‑path transit‑time ultrasonic flow meters deliver acceptable performance under ideal laboratory conditions with fully‑developed symmetric flow profiles. Nevertheless, real‑world industrial sites frequently suffer distorted velocity distribution caused by elbows, va...Read more -
Understanding Different Output Signals of Flow Meters for Industrial Integration
Effective data communication is critical for flow‑meter deployment across water supply, HVAC, chemical processing, marine systems and energy‑monitoring projects. Modern flow meters offer multiple output options to transfer measured data to PLC, SCADA, DCS, remote telemet...Read more -
What Causes a Flowmeter Reading to Fluctuate?
A flowmeter that shows a constantly changing or unstable reading can be frustrating, especially when the actual process appears to be running normally. However, flowmeter reading fluctuation does not always mean that the flowmeter is defective. In many applications, unstable readings are caused ...Read more -
Can Flow Measurement Be Performed on a Downward Vertical Pipe?
Yes, flow measurement can be performed on a downward vertical pipe, but the suitability of the installation location depends on the flowmeter type, whether the pipe remains full, and the actual pipeline configuration. This is an important consideration when installing an ultrasonic flowmeter or ...Read more -
Why Does Ultrasonic Flowmeter Installation Require Proper Sensor Spacing?
For a clamp-on ultrasonic flowmeter, installing the sensors on the outside of the pipe may look simple. However, one of the most important installation parameters is often overlooked: sensor spacing. The distance between the two ultrasonic sensors, also called transducer spacing, directly affect...Read more -
Why Is a Straight Pipe Length Important for Electromagnetic Flowmeter Installation?
When installing an electromagnetic flowmeter, selecting the correct installation location is just as important as choosing the right flowmeter size and lining material. One of the most common installation questions is: How much straight pipe is required before and after an electromagnetic flowme...Read more
