With continuous growth of tariffs for heating more and more people begin to think of economy. If your intentions are rather serious, then to think just right of installation of the heat meter. Its availability – reliable guarantee of the fact that you will not pay spare cash for heat which for various reasons has not reached you.
Instruction
1. All types of heat meters differ from each other in the principle of measurement of heat rate. There are turbine, vikhreakkustichesky, electromagnetic, wing, ultrasonic and kariolisovy heat meters which operation is based on pressure differential. Electromagnetic and ultrasonic models enjoy the greatest popularity. The operation principle of electromagnetic flowmeters is based that water has electric conductance. Water, passing through electromagnetic field of the coil, excites the electromotive force proportional to flow rate. Really it represents tube section with the electrodes which are built in it and the electromagnetic coil. Ultrasonic heat meters measure the difference of time of passing of signal through water depending on its speed. So at zero expense the difference of time intervals will be zero, and at maximum flow according to maximum. The design of the ultrasonic heat meter reminds electromagnetic, only instead of electrodes and the coil in it ultrasonic sensors are built in. Heat meters are installed on inputs in residential buildings.
2. Besides the heat energy going for heating they carry out measurement of the energy spent for heating of water in the GVS system. When reading surely consider temperature on intake and leaving the system. The volume of the spent heat energy can be measured in Gcal, kJ and MW.
3. All indications of heat meters are transferred to Gcal. So 1 Gcal corresponds 1.163 MW and 4.187 GDzh. Accounting of operating time of the device and also its operating time is obligatory. You can take readings of devices depending on their technical equipment – from the accumulative console, the notebook or from the printer. Do not forget for control near board to have the log-book of indications by means of which you will be able to check the sum exposed to you by the heatsupplying organization.
