Product Description
GB-1.6 Class B Micro ultrasonic gas meter
Genaral description
GB 1.6 type micro ultrasonic gas meter case using aluminum alloy die casting, the plastic made of high strength plastic molding and processing. This high quality materials and rational structure design to ensure that the product in the long-term work conditions, still can reach the target. Advanced micro ultrasonic principles through the change of piezoelectric sensor airflow, with high quality microprocessor calculation, therefore, is the ideal gas industry measuring instruments.
Structure theory
This product is in order to meet the market demand introduction of acoustic technology products, principle for air through aluminum alloy recessed, produce the vortex flow, its through the film piezoelectric patches, the vibration of the voltage signal, the voltage signal amplified, plastic and flow generation after proportional to the pulse signal. The monolithic integrated circuit to the pulse signal measurement and analysis, the conversion of the volume of a gas, single-chip microcomputer and the display and storage.
Application
GB 1.6 type micro ultrasound gas meter is suitable for natural gas, liquefied petroleum gas (LPG) and clean gas measurement.
Characteristics
Compact construction, advanced technology, accurate measurement, reliability and stability.

installation
1, before installation should read carefully the instructions, should by professional department of qualified for installation, and should comply with the GB 50028-93 town gas design the requirement of the specifications.
2, according to the pipeline position choice left or right entrance to the entry of the gas meter, mount transition joints according to the airflow direction in entering a pipeline connection.
3, in the installation, storage and handling, banned the cart before the horse and broke touch of strong earthquake, and table cover may not arbitrarily open, prevent water, sundry into.
4, after the completion of installation must be filled with 5 KPa + /-0.5 KPa air(or other reliable method) to air tightness inspection and confirm the rear can put into use.
Note
1, open flame is strictly prohibited or inflammable and explosive and poisonous and harmful gas leak detection!
2, it is strictly prohibited to disassemble the!
3, before the use must emptying pipe and air in the table!
4, found that when a flat immediately shut off the table before valve and open doors and Windows take a breath, and inform the department repair!
