The atmospheric tank’s difference is that the pressurized tank is an enclosed container with vapor pressure applied over the liquid, and the value of the vapor pressure may vary over time. Since the vapor pressure can not be neglected; therefore, it should be measured by both pressure inlets of the DP level transmitter. This could …

There are several temperature element types widely used to measure the temperature of a process substance. These types are categorized into mechanical temperature elements and electronic temperature elements. Mechanical temperature element uses the principle of thermal expansion, i.e. the element expands if the temperature rise and vice versa. Mechanical Based Temperature Element Solid element Bimetallic …
In the temperature measurement system, an electronic temperature instrument needs to connect to a control system. In contrast, RTD and thermocouple can be directly wired to the control system inputs card or via Temperature Transmitter for signal conversion. Most of the applications, the temperature transmitter are used to convert thermocouple or RTD signal into 4~20mA …
Bourdon Tubes A Bourdon tube is a metallic coil constructed from a metal tube, closed at one end and fixed to a pressure source at the other. It has the desired elasticity that makes the tube tends to deform to straighten under pressure. The pressure applied will results in the movement at the free end …
Another installation method for level measurement using a Differential Pressure level transmitter is by utilizing the diaphragm seal plus capillary tube. To determine the calibrated range for the Differential Pressure level transmitter, the filling fluid density within the capillary must be taken into account in the calculation since the fill fluid also creates hydrostatic force …
