KHET electromagnetic cooling and heating meter

Product Details

KHET electromagnetic cooling and heating meter

Typical application: It can directly measure cold, heat, and flow, and is widely used for distributed energy and central air conditioning metering.

Adopting high-precision temperature difference measurement circuit, temperature difference measurement is only related to the temperature variation value of platinum resistance, ensuring measurement accuracy.
No need for a separate calculator, it can directly measure cold and heat, and can automatically switch.
Suitable for measuring the heat and cold of various media, such as hot water, air conditioning water, refrigerant water, ethylene glycol, etc.
Has good lightning protection and anti-static power, as well as surge protection for power and signal lines.
Equipped with self diagnostic function, it can evaluate the operating status of the flowmeter in real time and improve maintenance efficiency.

Measuring fluids: central air conditioning water, heat exchange station primary and secondary network hot water, industrial refrigerant
Accuracy level: 0.5 (optional), 1.0
