Description
The 190PDE is a heat meter that utilises the 190PD ultrasonic flow meter and a pair of temperature probes to provide a convenient portable heat meter suitable for short term non-invasive heat meter and flow monitoring. Transducers provide a wide pipe diameter range from as small as 15mm up to 300mm and the meter itself can be configured for various different pipe materials and thicknesses. The temperature probes can be clamped to the pipe, or inserted into the pockets.
Features
- Ideal for clean fluid applications.
- Analog and digital outputs.
- Data logger with graphical display of data.
- Simple setup and installation.
- Built in help.
- Automatic speed of sound measurement and flow profile correction algorithm.
- Measure flow rate and energy consumption and flow within a pipe without cutting the pipe.
- Easy to attach clamp-on sensors.
- Suitable for all commonly used sonically conductive pipe materials and liquids.
- Clearly laid out high tactile response keypad.
- Very large flow measuring range with no complicated upper velocity limits.
The 190PDE portable heat meter is supplied with two matched precision temperature probes that are to be clamped to the flow and return pipes of the heating or cooling system. Alternatively, they can be inserted into pockets, if available or coupled to the pipe using heat transfer cement.
The unit measures the flow rate and the temperature difference, then using the internally stored specific heat capacity and density of the selected fluid at the measured temperature automatically calculates the energy flow rate and energy total. Very accurate measurements are possible easily meeting the accuracy requirements of EN1434.
