Cadillac® CU-TE Compact Ultrasonic Meter – Features
Key product features are as following:
- Simple installation that only takes a few minutes and a user-friendly system that makes for easy operation.
- The new external clamp on design provides the ability to read the flow rate without touching the measurement medium. In return, this can avoid pressure loss or media contamination problems.
- The clamp on feature saves time and costs by eliminating the process of cutting into the pipeline, which also eliminates needing to shut down other equipment for long periods of time to complete the installation.
- 3” 256*128 LCD screen to display a variety of measuring information.
- Supplied with temperature sensors, the calculator integrates the Cadillac® CU-TE to provide flexibility to meet all application needs.
- Has the option to be used as an ultrasonic cooling (heat) meter/btu meter/ energy meter to realize the measurement of energy.

FAQ for the Compact Ultrasonic Flow Meter
Q1: What is the CU‑TE Compact Ultrasonic Flow Meter used for?
The CU‑TE Compact is a non-intrusive clamp-on ultrasonic meter designed for flow and energy measurement of liquids in small pipe sizes (0.5″–2.5″). It’s ideal for hot and chilled water, oil, and clean chemical applications, especially in HVAC and energy monitoring systems.
Q2: How accurate is the CU‑TE Compact?
Out of the box, it delivers ±2% accuracy. After a quick field calibration, it can achieve ±1% accuracy. It offers strong repeatability and consistent performance across a wide range of flow rates.
Q3: What are the installation requirements?
Installation is fast and non-invasive. The sensors simply clamp onto the outside of rigid piping—no cutting, shutdowns, or process interruption. It works on stainless steel, copper, carbon steel, PVC, PP, PVDF, and similar materials.
Q4: Does the CU‑TE Compact require maintenance?
No. The meter has no moving parts, no wetted components, and is virtually maintenance-free. Built-in EEPROM data storage ensures long-term performance tracking for over a decade without degradation.
Q5: What outputs and communication options are available?
It includes 4–20 mA and pulse outputs as standard. It also supports Modbus RS-485 for integration with building or energy management systems. The unit includes a large LCD display for flow, energy, temperature, and totalization readouts.
Q6: Can the CU‑TE Compact be used as a BTU/Energy meter?
Yes. When paired with feed and return temperature sensors, it calculates BTU or energy usage by measuring flow, fluid density, enthalpy, and temperature differential. It’s suited for both heating and cooling applications.
Q7: What fluids and pipe types are compatible?
It measures clean liquids with no suspended solids or air bubbles, including water, oils, and most non-corrosive chemicals. Compatible with most rigid pipe materials such as copper, steel, PVC, and polypropylene.
Q8: What is the operational range for temperature and velocity?
The surface temperature operating range is 0 to 240 °F (non-freezing). It can detect flow at velocities as low as 0.33 ft/s, with adjustable reading intervals from 0.5 to 60 seconds.
Q9: How does the CU‑TE compare to traditional inline meters?
Unlike inline meters, the CU‑TE requires no pipe penetration, no pressure drop, and no fluid contact. It’s more cost-effective for retrofits and eliminates the risk of fouling or flow obstruction over time.
Q10: Is it physically durable and electrically protected?
Yes. The housing is rated IP65 for dust and water resistance. It’s designed to handle vibration, shock, and electrical risks with built-in protections for surge, short circuit, reverse polarity, and output overload.
