The ultrasonic flowmeter has a measuring range of ±32 m/s. With an accuracy of ±1.5 % f.s. for a pipe diameter of DN ≥50, ±3.5 % f.s. for a pipe diameter of DN <50 and a reproducibility of ±0.5 % f.s., the Portable Ultrasonic Flow Meter is a particularly precise measuring device. An installation aid is available for installing the sensors of the Portable Ultrasonic Flow Meter. The installation aid graphically displays the signal quality of the Portable Ultrasonic Flow Meter. In addition, it is graphically displayed whether the sensors of the Portable Ultrasonic Flow Meter are positioned at the correct distance from each other. To carry out flow measurements with the Portable Ultrasonic Flow Meter, the flow velocity, the volume flow and the volume are displayed after entering the pipe and medium specifications. The Portable Ultrasonic Flow Meter displays the measured values in a wide range of units. For example: m³, l, gal, igl, mgl, cf, bal, ib and ob. 

During a measurement, it is possible to record the measured values via the data logger function of the Portable Ultrasonic Flow Meter. Start and stop conditions and the storage interval from 1 second to 12 hours can be set for the Portable Ultrasonic Flow Meter. A memory point of the Portable Ultrasonic Flow Meter contains all measured values once. The measured values are stored on the 32 GB built-in memory of the Portable Ultrasonic Flow Meter. 10 million measuring points can be stored on the Portable Ultrasonic Flow Meter.

With the optional software, the recorded measured values can be read out from the Portable Ultrasonic Flow Meter. For analysis, the measured values from the Portable Ultrasonic Flow Meter can be displayed in tabular and graphic form. For further processing of the measured values from the Portable Ultrasonic Flow Meter, they can be exported in .csv file format. Alternatively, a PDF report can be created via the software. For simplified operation, the Portable Ultrasonic Flow Meter can be set via the software. A live view of the measured values from the Portable Ultrasonic Flow Meter is also possible with the software. 

In order to determine the amount of heat with the Portable Ultrasonic Flow Meter, two additional thermocouples are required. These are available with the PCE-TDS 200+. The two thermocouples of the Portable Ultrasonic Flow Meter are connected to the flow and return of a pipe system. Based on the temperature difference and the measured flow rate, the Portable Ultrasonic Flow Meter can determine the amount of heat. If required, the Portable Ultrasonic Flow Meter can calculate and display the costs per heat quantity unit simultaneously during the measurement. Thus, the Portable Ultrasonic Flow Meter is used, for example, in the inspection of heating systems.

The LC colour display of the Portable Ultrasonic Flow Meter has a size of 2.8" and is therefore easy to read. Optionally, the Portable Ultrasonic Flow Meter can be equipped with an ISO or DAkkS calibration certificate. 

PCE-TDS 200 S SENSOR

Small sensor pair for pipe diameters DN 15 ... 100 / 20 ... 108 mm. Suitable for particularly small pipes. The sensors have a particularly small dimension of 45 x 30 x 30 mm and a temperature resistance of -30 ... 160 °C. Thanks to the magnets on the underside, the sensors can be mounted on ferrous metals. In addition, the sensors for the Portable Ultrasonic Flow Meter can be connected to the pipe by means of detachable cable ties.
