EX3 is an energy meter designed for central air conditioning systems with two-way measurement of heat and cold.

· The shell is made of high-quality aluminum alloy, with good mechanical strength and beautiful appearance
· The temperature sensor uses a dedicated PT1000 high-precision platinum resistance, and is equipped with a precise measurement circuit to ensure high-precision temperature measurement
· The flowmeter is stuck on the outside of the pipe, no need to change the pipe
· No need for professional knowledge, installation and measurement can be completed according to the operation guide
· No moving parts, no pressure loss, can be installed and used without stopping production
