summary

In order to make the universal pressure instrument suitable for measuring the pressure of media with strong corrosion, high temperature, high viscosity, easy crystallization, easy solidification, and solid floating matter, as well as situations where it is necessary to avoid direct entry of the measuring medium into the universal pressure instrument and prevent sediment accumulation and easy cleaning, a diaphragm gauge consisting of a diaphragm isolator and a universal pressure instrument system must be used. Diaphragm gauges are mainly used to measure the pressure of fluid media in the production processes of industrial sectors such as petrochemicals, alkali production, chemical fibers, dyeing, pharmaceuticals, food, and dairy production.
