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.
n The flow meter should be installed in horizontal level, with the
display window facing upward.
n The water flows in the direction accordance with the arrow mark
n The diameter of the front and the back pipes should fit the flow
n 10DN straight pipeline and 5DN straight line should be saved (DN
is what we call the diameter of the heat meter)
n Must use the gasket and connecting pipeline specially designed
and manufactured by our company.
n The sewage filter and the valve should be fixed at both ends of
the flow meter for the convenience of filth removing, maintaining
n After the installation ,seal between the connecting bolt of the
capsule and the heat meter, between the temperature measuring ball
valve and the platinum resistor.
n Best water inflow and outflow pipeline options for easy fixing.
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.
heat meter 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
