The PCE-TDS 200+ S is a portable ultrasonic flow meter designed to measure flow rate, flow velocity and volume in pipes without cutting, opening or interrupting the installation. This version stands out because it also includes thermal measurement, making it especially valuable for heating systems, thermal circuits and energy audits.

With a measurement range of ±32 m/s, high repeatability and different measurement methods, the instrument delivers reliable results across a wide range of applications. The installation help menu guides correct sensor positioning and graphically displays signal quality and the ideal sensor spacing, simplifying field work and reducing configuration errors.

After entering the pipe and fluid parameters, the display shows flow velocity, flow rate and volume. Because this version includes thermal measurement, it can also display temperature, thermal power, thermal energy and even costs, based on the temperature difference between supply and return and the measured flow.

The built-in 32 GB memory stores up to 10 million values, with logging intervals configurable from 1 second to 12 hours. Optional software allows users to read data, view graphs and tables, export to CSV, generate PDF reports and monitor measurements in real time. The instrument is optionally available with an ISO or DAkkS calibration certificate.

Key benefits

• Ultrasonic measurement without physical intervention in the pipe.
• Integrated thermal measurement with thermal power and thermal energy calculation.
• 32 GB internal memory for up to 10 million logs.
• ±0.5% repeatability of the measured value.
• Graphical help for correct sensor installation.
• Displays flow velocity, flow rate, volume, temperature, thermal power and thermal energy.
• Compatible with multiple liquids, pipe materials and internal linings.
• USB-C for data transfer and charging.
• Optional software for analysis, export and PDF reports.
• Optional ISO or DAkkS certification.

Recommended applications

The PCE-TDS 200+ S is especially suitable for temporary measurements, performance verification and thermal analysis in installations where physical pipe intervention is not desirable. It is recommended for:

• Heating system verification
• Thermal and hydraulic circuits
• Thermal energy audits
• Commissioning and installation validation
• Industrial maintenance and diagnostics
• Monitoring of flow, consumption and energy costs

Technical and functional advantages

The main advantage of the PCE-TDS 200+ S is the combination of flow measurement and thermal measurement in the same instrument. This makes it possible to analyse not only the hydraulic behaviour of the installation, but also the thermal energy transfer, making the device much more complete for energy efficiency and technical control applications.

Its ability to calculate thermal power, thermal energy and costs, combined with data logging and export for later analysis, makes this flow meter a highly valuable tool for maintenance technicians, energy auditors, engineers and professionals responsible for optimising thermal systems.
