Brand Name: Hiwits
Model Number: DN20-32-A
Place of Origin: Shandong, China (Mainland)
Applicable Scope
Hiwits heat meter is applicable for calculating heat(cold) consumption of residential house and public construction, and also used to calculate central air-condition’s cold supply. To be installed in heat(cold) exchange annular system, measuring heat(cold) consumption of heat exchange system with the media of water.
Characteristics
1. High waterproof-qualified silicone ring, waterproof button and IP67 waterproof tapered en, make sure the heat meter can work reliable in humid condition for a long time.
2. Sepearte Structure-the calculator can be separated from the host heat meter, which makes no dead angel for reading; the calcualtor can be mounted on the wall.
3. Anti-clogging-Straight Route tube, anti-incrustation.
4. Long Operating Life-Transverse-axis Impeller system, smoothly rotation with little incrustation, and the heat meter keeps long-time accurate.
5. Acquisition-Using Non-Magnetic signal acquisition technology, reliable and stable.
6. Little Pressure Loss---The pressure are far more less than national-level rated flow.
7. Convenient Installation---There’s no limitation for the installation direction, horizontal and vertical are both available.
8. Powerful Functions---Multi-function liquid crystal display, error warning, RS485, MBUS and Pulse.
9. Easy for Examination and Repair---proprietary battery box design, convenient for changing the battery.
10. High Quality---High quality with Low power consumption.
