Product Introduction
This RC type ultrasonic wave heat meter is an instrument measuring and displaying heat released /absorbed by the heat carrying liquid in heat exchanging circuit.The unit of heat measurement is KW·h. It consists in three parts , namely flow sensor, temperature sensor and calculator.
Application and Warnings
The installation requirements of the heat meter
Before installation, check the pipelines in the cleansing system thoroughly and remove silk, hemp ,sand ,gravel and any other masses to avoid any flow hindrance.
The installation of temperature sensor
One temperature sensor with red tag is to be installed inside the heat measuring meter, the other sensor with blue tag is to be built inside the temperature measuring ball valve.
The lead wire of the temperature sensor is not allowed to be lengthen, shorten or changed casually.
Performance
Household mechanical heat meter bears the features of high accuracy, steady operation, long using life, no subjecting to inferior water and low maintaining cost .It can be widely used in concentrated or regional heat supply system or separate household measuring in central air condition system
