    Installation and Attentions

    The heat meter both can be installed in Inflow pipe or Return flow pipe (factory default installed in the inflow pipe, if need to install on the return pipe, must be clearly indication before the factory during the production). When installation, should pay attention to the flow direction of medium is as the same as the arrow on the heat meter pipe body.

    Special note: no matter the heat meter installed on inflow pipe or return flow pipe, the temperature sensor should be properly connected ( red label for inflow pipe, blue label for return pipe)

    Instrument Common Problem

    The meter cannot work normally

    Heating system is working or not;

    Globe valve is opened entirely or not;

    the pipe is blocked or not;

    the lead seal is complete or not;

    Battery is good or not;

    heat meter isn’t counting

    ①,heat meter reversed installation

    ②,transducer cables are broken

    ③,the filter is be blocked on heat supply pipe of in the resident room

    How to determine the filter whether block?

    Inflow temp. is normal, return flow temp. is too low, the temp. difference of inflow and return flow is more than 10°, flow rate is too low(m3/h), or now flow rate, usually the filter is blockage, or user does not use.

    Solution:Close the valve (inflow and return flow valve), remove the filter, to observe whether filter is black, clean filter and inside of it, then install the filter, open pipe valves, wait 3 mins to check whether the flow rate and temp. is normal.

    Heat meter data abnormal or jumping

    ①,Installation position is not correct, down water level

    ②,Front and back straight pipes are too short, bend is too big, front pipe diameter is

    changing bigger.

    Heat meter has flow quantity, no heat, or heat is very big

    ①,Without heat is usually reversed installation of inflow and return flow temp. sensors

    ②,Heat is very big, because the temp. sensor measure temp. incorrectly, temp. difference is very big.

    Heat meter abnormal temp., or the temp. is 0

    ①,the temp. sensor cable is broken

    ②,Temp. sensor stainless steel casing is broken.
