Product introduction:
Ultrasonic gas meter is a new type of all electronic metering combustion which uses the time difference of ultrasonic transmission in the medium to measure Gas meter, with high reliability, high precision, temperature and pressure compensation and other endogenous functions.
Technical principle:
Time difference method is adopted in ultrasonic measurement, and its working principle is to use a pair of ultrasonic transducers to alternate in phase (or at the same time) send and receive ultrasonic wave, and indirectly measure the fluid by observing the time difference between forward and reverse flow propagation of ultrasonic wave in the medium Flow rate, and then through the flow rate to calculate the flow rate of an indirect measurement method.

Installation and safety matters
1.Before installation, the gas meter should be inspected first for appearance and then for sealing performance, so as to prevent installation and use of the gas meter that may cause damage during transportation.
2.When installing the gas meter, it should be noted that the distance between the center of the pipeline connected with the gas meter should be consistent with the distance between the center of the gas meter. It should not be forced to connect and twist to avoid leakage at the connection of the gas meter.
3.The gas meter should have sufficient safe distance from the stove and other fire sources.
4.Keep in mind：The air in the pipeline and gas meter should be emptied before ignition.Gas mixed with air can easily explode when it meets spark.
5.During transportation, storage and installation of gas meters, care should be taken to prevent falling upside down and water entering.
6.The fuel gas used should meet the requirements of the national standards and should not contain moisture. The condensed water in fuel gas will freeze the table and cannot operate normally
7.In order to avoid condensate water into the gas meter, the gas meter should be installed horizontally at the high point of the pipeline when installation should pay attention to the top of the case arrow, indicating the direction of gas flow, should not be connected to the reverse (because the table has anti-retrograde device).
8.The gas meter should be installed in a dry and ventilated place. It is strictly prohibited to install the gas meter in the
bedroom and bathroom, and should not be installed in the place where the gas meter is seriously corroded.
9.When the pipeline system leaks, it is forbidden to leak the open fire. When the pilot fire is carried out, the air in the gas
meter must be discharged to prevent accidents
10.In case of malfunction, please do not disassemble by yourself, please ask the technical personnel of gas company for
maintenance.
11.In case of gas leakage, first close the front table valve, immediately open doors and Windows ventilation.
12.Do not use open fire leak detection, carefully with soap and water leak detection.
13.This meter can not be used in the use of strong caustic soda gasoline alcohol solvent cleaning.
