The Ultraflux Uf 811 ultrasonic flow meter is a high-performing “clamp-on” solution for permanent liquid flow applications.
The Ultraflux Uf 811 Clamp-on Ultrasonic Flow Meter is a non-intrusive flow meter that uses transit-time ultrasonic technology to calculate flow velocity and volumetric flow rate.
This ultrasonic flow meter uses two transducers to alternately send and receive ultrasonic signals, which measures the transit time difference between the transmitted and received signals, directly determining the liquid flow rate.
The Uf 811 ultrasonic flow meter has a wide range of pipe diameter compatibility, from 10mm to 10,000mm, making it a cost-effective replacement for existing in-line or insertion flow meters that are expensive to repair or replace. Additionally, the ultrasonic flow meter is capable of measuring all conductive and non-conductive liquids including domestic water, waste water, chemicals, demineralized and purified water, hydrocarbons, and any other transparent liquids.
The Uf 811 Ultrasonic Flow Meter uses advanced transit-time ultrasonic technology to calculate flow velocity and volumetric flow rate. It is sensitive to high and low flow velocities, ensuring accurate and reliable results even in extreme conditions. The ultrasonic flow meter is equipped with a user-friendly interface and can be easily programmed and configured via USB port. Learn more here.
The UF 811 ultrasonic flow meter uses advanced digital signal processing to offer a wide dynamic measuring range and is sensitive to high as well as low flow velocities. This guarantees accurate, stable and reliable results even in extreme measurement conditions.
With advanced digital signal processing, the Uf 811 ultrasonic flow meter offers a wide dynamic measuring range and is sensitive to high and low flow velocities, ensuring accurate, stable, and reliable results in extreme measurement conditions. Furthermore, it is an ideal solution for water leak detection in pipe networks in utilities and chilled water systems, as it can detect liquid velocities down to ±0.03 ft/s.
As a non-invasive flow meter, the Uf 811 requires no pipe cutting, welding, or shutting down of processes or systems, making it a practical solution for retrofit installations on existing pipe networks. It also reduces the installation costs to a minimum and overall cost of ownership of the flow meter. Learn more here.
With all industry standard communication protocols such as serial link RS232 or RS485 to JBUS/MODBUS, the Uf 811 offers bidirectional field communication and real-time diagnostics. The ultrasonic flow meter is user-friendly with a simple interface and easy commissioning process that can be programmed and configured via USB port. On-screen signal visualization and diagnostics provide troubleshooting capabilities on-site.
