E5 ULTRASONIC ENERGY METER

Clamp-on type ultrasonic energy meters for flow and heat consumption measurement.

 

Introduction

As an inhabitant of the 21st century, we try to be "smart & green", so the Smart Building has become a very popular concept among citizens and urban planners.

 

Climate control, or HVAC system plays the vital role in the whole building management system, to support the this, a lot of electricity is needed, it is important to measure and control energy consumption accurately, in times of increasing energy costs .

 

Energy Meters(commonly referred to as BTU meters or heat/cool meters), that is used to measure the energy consumption of heat/chilled water, for both commercial and industrial and office buildings.

 

Model E5 is a economical wall-mounted ultrasonic energy meter, basic on Tansit-time technology, can be an ideal choice to integrate with a wide range of applications in HVAC, heating/cooling energy production.
