Using the Transit Time measurement principle, the CUTT Clamp-On Ultrasonic Flow Meter fastens on the outside of vertical or horizontal pipes ranging in size from ½” through 48”.  Housed in a water- and dust-tight NEMA4X polycarbonate enclosure, the Clamp-On Ultrasonic Flow Meters offer Isolated 4-20 mA and 0-5 V analog output. The non-intrusive flow measurement allows measurement of the most “corrosive liquids” that would damage standard flow meters. Clamp-on transducers can accommodate all common pipe materials at diameters from 0.5” to 48” and withstand temperatures from -40°F to 300°F. The meter comes with free datalogging software for data display, manipulation, analysis, and exporting.  

Applications include:

  • Food processing
  • Chemical processing plants
  • Oil refineries

Non-Contacting Flow Measurement
Ultrasonic transducers clamp on the outside of pipes, allowing for installation without system shutdown, and produces no pressure drop.

User-Friendly Operating System
Built-in keypad and simple menu system for fast and easy programming of pipe diameter, pipe material, liquid type, and measurement units. All settings, calibration values, and totalizer are retained during power interruptions.

Industrial Automation Protocols
Modbus RTU and HART communications allow for instantaneous flow rate, volumentotal, run hours, and diagnostic information.

Wide Range of Applications
Compatible with a wide range of pipe materials and fluids, including treated, raw, cooling and lowconductivity water, water/glycol solutions, chemicals, and hydraulic, diesel and fuel oils.

Safe in Wet Locations
IP67 (NEMA 6) rating allows for safe operation during temporary periods of submergence.

N/A The Transit Time Flow Meter measures flow from the outside of pipes. It works by measuring the time of flight difference for ultrasonic sound pulses transmitted from one transducer to another. Depending on the mounting configuration, the signal may cross the pipe once, twice, or four times. The time between transmitted and received signals is precisely measured by the flow meter. Ultrasonic signals are sent upstream and then downstream with the transducers alternating their functions as transmitters/receivers.

The transit time in the direction of flow is always faster than the transit time against the flow. By comparing these differences with precision timing circuits, the meter is able to accurately calculate the flow rate. Because the ultrasonic signal is transmitted across the pipe, an average of the flow profile is calculated.

The transducers can be mounted on vertical or horizontal pipes, and the pipe must be full. Choice of V, Z, or W mounting method depends on the application and pipe diameter.
