This flowmeter is a clamp-on type ultrasonic flowmeter for liquids, developed with the concept of 'completely construction-free.' It allows for easy and convenient flow measurement, making it ideal for expanding the measurement range of utility and energy fluids (such as water and hot water) in construction and commercial facilities. By visualizing the flow in every corner of branch pipes, which was previously difficult to implement due to costs and construction periods, it is expected to contribute to energy-saving promotion and decarbonization efforts.
Since it is a clamp-on type that is attached to the outside of the piping, no piping work is required. Maintenance bypass piping is also unnecessary.
One model supports 8 different pipe diameters (nominal diameters: 25A to 100A), from small to large. This is economical because there is no need to stock models corresponding to each pipe diameter for spare parts.
No tools, attachments, or grease are required for installing the flowmeter. It can be fixed to the piping using the two included bands with hand-tightened screws.
It can operate continuously for about 10 years with the built-in battery, so external power equipment and electrical work are not necessary.

※1: Homogenous liquid through which ultrasonic waves propagate and which does not contain a large amount of air bubbles (Measurement may not be possible depending
on the piping material or diameter, or sound velocity of the liquid)
※2: The above flow ranges are reference values for Sch10S size according to JIS G 3459: Stainless Steel Pipes.
The actual flow range varies depending on the inner diameter of the pipe used.
※3: Guaranteed values based on our inspection environment
Errors may occur depending on the type and condition of the customer’s piping, type of fluid, fluid temperature, etc.
※4: Accuracy when electrical noise is applied to the cable (under EN/IEC 61000-4-6 environment of EN/IEC 61326-1) is as follows (only for no-voltage contact pulse
specification). ±6.0% of RD (10 to 100% of max. flow rate), ±0.6% of FS (0.3 to 10% of max. flow rate)
(Note) This product cannot be used in explosionproof areas. In addition, it cannot be used for “transaction and certification” purposes.
