DY glycerin filled pressure gauge is specially designed for severe pulse and high mechanical vibration environment. By filling high purity glycerin to achieve excellent damping effect, it ensures stable pointer reading and prolongs the life of internal movement. As a source production factory with a history of more than 30 years, Hangzhou East Asia Instrument has more than 300 professional manufacturing equipment and more than 10 automated production lines, which can eliminate all middleman costs and provide you with highly competitive ex-factory prices and fast delivery guarantee.
Glycerin-filled pressure gauges are mainly used in hydraulic systems, petroleum minerals, heavy machinery manufacturing and electric power devices.
The DY instrument uses the physical viscosity of the liquid to produce strong damping by filling high-purity glycerin in a stainless steel housing. This can effectively suppress the sharp shaking of the pointer caused by pipeline vibration or pressure pulse, and ensure that the field operator can still obtain accurate readings under severe conditions.
It is stamped with high-quality 304 stainless steel, with precision sealing rings and thickened lenses to meet IP65 protection standards. This fully sealed structure not only prevents the filling liquid leakage, but also blocks the erosion of the external water vapor, dust and corrosive gases on the internal movement of the instrument.
The internal movement is completely immersed in the lubricating glycerin. This design not only reduces the mechanical wear of gears and connecting rods under frequent actions, but also plays the role of continuous lubrication and anti-corrosion protection, so that the average working life of the instrument far exceeds that of ordinary dry pressure gauges.
DY provides a variety of installation methods with radial, axial and front or rear edges. The interface thread covers international mainstream standards such as metric system, German standard and American standard. Whether it is pump set matching or narrow space installation, can provide accurate matching specifications.
Each 1 DY oil-filled pressure gauge has undergone rigorous sealing test and pressure calibration before leaving the factory. Relying on more than 300 sets of production equipment and perfect quality control system in the factory, it is ensured that the products still maintain high linearity and repeatability error control under full load continuous working condition.
Selection of dehydrated high-purity glycerin, effectively avoid the instrument in the ambient temperature fluctuations in the internal condensation of aerosol. This ensures that the dial window always maintains a high degree of transparency in different climatic conditions, greatly reducing the risk of misreading by inspectors.

DY glycerin-filled pressure gauge relies on Hangzhou East Asia instrument manufacturing accumulation of more than 30 years, in the sealing technology using double-layer leak-proof process, to solve the industry’s common oil-filled meter oil leakage pain point. Compared with similar products, our stainless steel shell thickness increased by 15%, can withstand stronger mechanical impact without deformation.
Suitable for distributors looking for high-quality, stable performance and price advantages of the source factory products, DY’s large-scale production capacity can meet the demand for large-scale orders.
Suitable for technicians who design hydraulic stations or power units, the high shock resistance of the product ensures that the system can still safely monitor pressure under instantaneous high-voltage pulses.
It is suitable for updating instruments in corrosive environments such as oil drilling and refining pipelines. The fully sealed stainless steel material can meet the weather resistance requirements of outdoor long-term work.
It is suitable for factories that need to provide supporting instruments for the whole machine. DY supports customization of various customized threads and LOGO private labels to enhance the brand value of host products.
During installation, a wrench must be used to act on the hexagon plane of the connector, and it is strictly prohibited to directly grasp the instrument shell for rotation. Ensure that the thread specification matches the field pipe, using sealing gaskets or raw material tape if necessary.
Once in position, the tip of the black rubber filler plug at the top of the instrument needs to be cut open or moved to the vented position. This can balance the pressure inside and outside the case, eliminating the effect of internal pressure on accuracy due to temperature difference.
The recommended operating pressure is between 1/3 and 2/3 of the gauge range. Should try to avoid the instrument in the range of more than the upper limit of the state of long time work, to prevent the internal spring tube plastic deformation.
Regularly observe whether the liquid level in the meter drops obviously, and check whether the dial window is blocked by oil stains. If the color of the filling liquid is severely turbid, contact the manufacturer for liquid replacement or re-calibration of the accuracy.
