summary

The HL series hot (cold) gauge consists of a heat calculator, a hot water flow meter, and a paired temperature sensor. It is an intelligent measurement display system composed of a low-power microcontroller and a nine bit LCD display, which displays heat, cold, flow, inlet temperature, return temperature, and inlet temperature difference, respectively. It is an ideal measuring instrument for central heating and central air conditioning billing measurement.

characteristic

The heat calculator uses low-power technology, internal power supply, and high-definition wide temperature LCD display.

The temperature paired sensor uses Pt1000 to ensure measurement accuracy and stability, and is equipped with a protective sheath for good thermal conductivity and durability.

○ It can automatically convert cold and heat, suitable for central air conditioning charging.

The overall heat meter is easy to install and aesthetically pleasing, while the split type heat meter is flexible to install and has a wider range of applications.

The accumulator adopts a fully rotating design, and the display screen can rotate freely for easy reading. It can be used in various installation environments such as indoor and pipeline wells.
