Designed for “difficult” Liquids
The UF D5500 Doppler flow meter works best in applications that would defeat regular contacting flow meters. Because the sensor is mounted on the outside of the pipe, it is unaffected by abrasives or harsh fluids. There is no obstruction to flow and no pressure drop.
Enhanced Signal Processing and Industrial Noise Immunity for Reliable Accuracy
The UF D5500 Doppler flow algorithm filters out background noise and interference. The high-speed digital signal processor discriminates against weak and distorted signals for increased reliability and accuracy.
Easy to Install
Each UF D5500 Doppler Flow Meter includes a clamp-on ultrasonic sensor, an adjustable stainless steel mounting clamp and sensor coupling compound.
The sensor fits on the outside of any pipe diameter 12.7 mm (½”) or larger. It takes just a few minutes to install. There is no need to shut down the flow.
Simple, Single-Head Sensor Design
Ultrasonic signals are transmitted and received from a single-head sensor. The mounting clamp (included) ensures correct sensor alignment on horizontal or vertical pipes. The UF D5500 automatically self-tunes to the cable length up to 152 m (500 ft.).
Works on most Pipes
The UF D5500 Flow Meter measures flow in PVC, carbon steel, stainless steel, cast iron, HDPE, ductile iron, and concrete-lined ductile iron… any pipe material that conducts ultrasound.
Doppler signals cannot transmit through pipe walls containing air pockets (e.g., concrete or wood) or loose pipe liners (with an air gap between the liner and pipe wall).
Backlit Display with Easy-to-Use, 5-key Menu System
Configuration is easy with the new UF D5500 user-friendly menu system. Press the arrow keys to scroll through menus, change settings and enter calibration values. You can select English, French or Spanish menus, enable a password to protect settings and control the brightness of the digital display.
Reverse Flow Measurement
The UF D5500 measures flow in either direction and displays positive or negative values. You can control the Totaliser to subtract reverse flow or totalise forward flow only. The 4mA setting can also be adjusted to a negative flow setting.
26 Million Point Data Logger NEW Standard Feature
The UF D5500 Doppler Flow Meter comes standard with a built-in 26 million point data logger. It includes Windows software to display flow charts and tables, and to create dynamic flow reports. Just plug in a standard USB flash drive, and log files are downloaded automatically.
Principle of Operation
The UF D5500 Sensor transmits continuous high-frequency sound through the pipe wall into the flowing liquid. Sound is reflected back to the sensor from particles or gas bubbles in the liquid. If the liquid is flowing, the reflected sound returns at an altered frequency (the Doppler effect).
The UF D5500 continuously measures this frequency shift to measure velocity accurately.
