Long Service DN15-40 Temp Display Ultrasonic Heat Water Meter with Wide Measurement Range

Features

1. Accurate measurement: the use of high-quality transducers, PT1000 high-precision platinum
resistors, and advanced electronic measurement technology ensure high accuracy and stability
of flow measurement
2. Accuracy level: Level 2
3. Strong anti-interference ability: completely unaffected by impurities, chemical substances
and magnetic materials in the medium
4. Long service life: no mechanical parts, no wear, low maintenance cost
5. Data remote transmission function: remote meter reading can be realized through M-bus bus
and RS-485 bus
6. Automatic error diagnosis function: There is an error message prompt function under
abnormal conditions to ensure safe and accurate operation
7. Large-capacity data storage function: can save the historical settlement data of the last 24
months
8. Easy to use: the calculator head can be detached and installed horizontally for easy reading

battery, service life of more than 6 years
10. Calculating cold and heat: integrates cold and heat measurement, automatically judges
heating and refrigeration can be measured according to water temperature
11. Installation location: optional installation of inlet and return pipes for easy construction
12. Easy installation: optional horizontal or vertical installation
 

Installation requirements

1. Pay attention to the direction of the arrow mark on the flowmeter to make the water flow
direction consistent with the arrow direction
2. Do not block the valve port with hemp, raw material tape and other debris during installation
3. Handle with care during the installation process and strictly prohibit brutal operation to
prevent man-made damage
4. The HVAC pipeline should be cleaned before installation, and the front end of the flow
meter should be equipped with a dirt filter and a shut-off valve to remove dirt and repair and
replace
5. There should be a straight pipe section not less than 10 times the nominal diameter at the
front end of the heat meter, and a straight pipe section distance not less than 8 times the
nominal diameter at the back end.
6. The temperature sensor with the red label is installed on the high temperature pipeline, and
the temperature sensor with the blue label is installed on the low temperature pipeline. The
lead wire of the temperature sensor shall not be increased or decreased at will
7. All parts of the heat meter (including heat meter parts, temperature sensor parts and
calculator parts) should be installed in a position to avoid exposure, water flooding, freezing
and electromagnetic pollution, and be easy to disassemble
