Ultrasonic BTU Meters: Accurate Energy Measurement for Modern Systems

In an era where energy efficiency and cost accountability are paramount, Kaifeng Oasis Instrument Co., Ltd. empowers industries with cutting-edge solutions like the OUF Series Ultrasonic BTU Meters. Combining non-invasive measurement, high precision, and flexible OEM customization, our technology redefines thermal energy monitoring for HVAC, district heating, and industrial applications.

How Ultrasonic BTU Meters Work

The OUF Series utilizes a proven three-step process to measure thermal energy:

1. Ultrasonic Flow Measurement

• Transit-Time Technology: Clamp-on transducers measure flow velocity by comparing upstream/downstream ultrasonic pulse times.

• Non-Intrusive Design: No pipe modifications or pressure drop, ideal for retrofit projects.

2. Temperature Differential Analysis

• Dual RTD Sensors: Measure supply and return temperatures with ±0.1°C accuracy.

ΔT Calculation: 

                     $\mathrm{\Delta }T=T_{\text{in}}-T_{\text{out}}$  

determines energy transfer efficiency.

3. Energy Calculation

$$Q=q\cdot \rho \cdot c\cdot \mathrm{\Delta }T$$

Where  $Q$ = thermal power,  $q$ = flow rate,  $\rho$ = density,  $c$ = specific heat.

Advantages of the OUF Series Ultrasonic BTU Meters:

Unmatched Accuracy & Reliability:

• ±1% measurement precision for billing-grade results.

• Auto-compensation for fluid properties (temperature, density).

Robust Design:

• IP68-rated sensors for harsh environments.

• Wide temperature range (-30°C to 160°C).

Cost-Effective Installation:

• Clamp-on design reduces downtime and labor costs.

• Compatible with pipes from DN15 to DN6000.

OEM Flexibility:

• Customize housings, software interfaces, and communication protocols (Modbus, Mbus and more).

• Brand with your logo for seamless integration into your product ecosystem.

Applications of OUF Series BTU Meters:

• HVAC Systems: Monitor chiller/cooling tower efficiency.

• District Energy: Allocate costs accurately in heating/cooling networks.

• Industrial Processes: Track thermal energy in manufacturing and chemical plants.

Limitations and Considerations:

• Fluid Requirements: Best for clean liquids (water, glycol); not suitable for slurries.

• Installation: Requires trained technicians for optimal transducer alignment.
