3.1summary
MAG-11 electromagnetic heat meter (hereinafter referred to as "heat meter") is a
product integrating the measurement of air conditioning water flow, heat and temperature
difference, which is suitable for cold / hot water air conditioning billing system.
The converter, electromagnetic flow sensor and supply / return water temperature
sensor form a heat meter. The converter can be installed independently or assembled
on the electromagnetic flow sensor.

3.2 Product features
Unimpeded detection: the pipeline is unobstructed, will not block the flow, will not
cause pressure loss, save the power consumption of the water pump, and does not need
a filter.
High precision measurement: high precision A/D conversion circuit is adopted, and the
flow measurement error can be within ± 0.5% of the actual flow.
