Integrate into your management system to provide remote measurement services.
The ST505 Ultrasonic Flow Meter uses the most reliable digital signal processing technology, transmitting flow measurement for a wide range of liquid and pipe sizes with high accuracy and reliability. Combined with outstanding performance transducers and higher industrial-level materials, Flo-Instruments flow meters can operate for long periods without concern.
Clear menu display selections make using the instrument very convenient. Clamp-on transducers make the unit more flexible over a wide range of applications.
The ST505 ultrasonic flowmeter is based on Transit-Time technology, which provides high measurement accuracy. The ST505 uses a clamp-on transducer that collects flow data simply by clamping onto the outside of the pipe. It never comes into contact with the fluid, so it will not cause liquid pollution, pressure reduction, leakage, or similar issues.

The "V" method is considered the standard method. It usually gives a more accurate reading and is used on pipe diameters ranging from approximately 25 mm to 400 mm (1" ~ 16"). It is convenient to use but still requires proper installation of the transducer, contact on the pipe at the pipe's centerline, and equal spacing on either side of the centerline.
V method installation
The signal transmitted in a "Z" method installation has less attenuation than a signal transmitted with the "V" method. This is because the "Z" method utilizes a directly transmitted (rather than reflected) signal that transverses the liquid only once. The "Z" method is able to measure on pipe diameters ranging from 100 mm to 3000 mm (4" ~ 120").
Z method installation
With the "N" method, the sound waves transverse the fluid twice and bounce three times off the pipe walls. It is suitable for small pipe diameter measurement. Measurement accuracy can be improved by extending the transit distance with the "N" method (uncommonly used).
N method installation
As with the "N" method, measurement accuracy can also be improved by extending the transit distance with the "W" method. The sound wave transverses the fluid four times and bounces four times off the pipe walls. It is suitable for very small pipes (diameter less than 50 mm / 2").
