  • A Brief Discussion of Pressure and Vacuum Levels

    A vacuum gauge is used to measure the pressure in a vacuum—which is typically divided into two subcategories, high (i.e., hard) vacuum and low (i.e,, soft) vacuum. To select the right pressure device for a specific application requires one to know the desired pressure range and the capability of the pumping system to achieve the desired pressure.

  • Can you measure vacuum using a gauge pressure range

    A gauge pressure range is not suitable for measuring high vacuum pressures, since you can only use a full vacuum range device, which compromises the accuracy and resolution so much that the errors are greater than the difference between full vacuum and the high vacuum reading.

  • Protect Tanks from Overpressure and Vacuum | AIChE

    Tank Overpressure and Vacuum ScenariosTank Pressure- and Vacuum-Relief SystemsDispersion Consequence ModelingFinal ThoughtsAPI Standard 2000 defines the venting requirements for atmospheric and low-pressure storage tanks for both overpressure and vacuum. The standard covers causes of overpressure and vacuum, including additional scenarios to be considered for refrigerated tanks (Table 2) (2). Note that the causes of vacuum are often the inverse of analogous causes of overpressure. Overpressure scenarios fall into five general categories: 1. liquid inflow caused by normal liquid flow to a tank or by unexpected diversion of liquid to a tank (e.g., liquid heat-transfer fluid ingress from a leak), which can displace the tank vapor space (i.e.,outbreathing) or overfill the tank 2. vapor inflowcaused by the malfunction of a control valve or of a regulator on a tank blanketing system to the open position, breakthrough of pressurized motive gas used for liquid transfer, or mechanical failure of an internal steam heating coil or steam jacket 3. change in heat transfer caused by high ambient temperatures or incre...
