FAQ
COMMON PROBLEM
What liquids can FlowT ultrasonic flow meters measure?
What is the difference between V method and Z method?
Can one portable ultrasonic flow meter be used on different pipes?
What are the main advantages of clamp-on ultrasonic flow meters?
Are ultrasonic flow meters suitable for dirty liquids?
Can FlowT ultrasonic flow meters provide output signals?
FlowT ultrasonic flow meters are commonly used for water, cooling water, hot water, industrial water, and other clean or relatively clean compatible liquids. Final suitability depends on liquid condition, pipe material, temperature, and installation environment.
The V method is commonly used for small and medium pipes with good signal conditions. The Z method is often used for larger pipes or applications where signal transmission needs to be improved.
Yes. A portable ultrasonic flow meter can be used for measurement on different pipes, but each measurement point requires correct pipe parameter input and proper sensor installation.
Main advantages include non-invasive installation, no pressure loss, no moving parts inside the pipe, reduced installation work, and suitability for existing pipeline measurement.
Transit-time ultrasonic flow meters are generally more suitable for clean or relatively clean liquids. Excessive bubbles, heavy solids, scaling, or unstable flow conditions may affect signal quality and measurement performance.
Yes. FlowT ultrasonic flow meters can be configured with common industrial output and communication options according to model and project requirements, such as analog output, pulse output, relay output, and RS485 Modbus communication.
