High quality piston flowmeter

High quality piston flowmeterIt was newly developed, designed, and manufactured by my research institute in accordance with the requirements of the national "piston pressure gauge" calibration regulations. Due to the use of tungsten carbide material with high hardness and low temperature coefficient of linear expansion as the key component of the piston pressure gauge, the wear resistance of the piston is improved, resulting in minimal deformation (negligible) under pressure and extremely stable performance. The working medium of the piston uses diisooctyl sebacate, which gives the pressure gauge a sensitivity of *.
Due to the adoption of new materials, technologies, and processes, the technical indicators of the new piston pressure gauge have been improved
Greatly improved. Thus, it is widely used to calibrate pressure instruments such as digital pressure gauges, precision pressure gauges, pressure transmitters, and pressure sensors. JY series piston pressure gauge * JJG59-2007 Verification regulation for piston pressure gauge

High quality piston flowmeterPerformance characteristics:

1. Both the piston and the piston cylinder are made of high-strength, high hardness, and low-temperature linear expansion coefficient hard alloy tungsten carbide material that has been carefully ground. The working environment has a wide temperature range and stable performance of 20 ± 5 ℃.
2. The center of gravity of the load is low, and the weight is directly added to the piston through the hanging basket. The piston runs smoothly, with minimal pressure fluctuations and accurate readings.
3. For pressure transmission media above 25MPa, diisooctyl sebacate with very low viscosity is used to ensure the sensitivity of the pressure gauge.
4. All weights used in the pressure gauge are made of non-magnetic stainless steel material.
5. The working position of the piston is monitored by a displacement sensor, and the up and down stroke of the piston is ± 1.5mm. The instrument display has the advantages of sensitivity, visibility, and accuracy.
6. Wide range, with a basic error of ± 0.02% or ± 0.05% at a lower limit of 1MPa. One KY100 pressure gauge can withstand the current domestic measurement upper limits of 6, 60, and 100MPa for use with three pressure gauges.
7. Pressure adjustment is lightweight and effortless, even at a pressure of 100MPa.
