Flange mounted level transmitters introduction

Flange mounted level transmitters are essentially DP transmitters where a process mounting flange is used instead of the NPT process connection on a DP transmitter. These transmitters are used to measure fluid level in vented or pressurized tanks.

The mounting flange is connected to the High Pressure port, and the Low Pressure port is open to atmosphere, or connected to pressure line from the top of the tank. Smart transmitters have the benefit of adjustable measuring span or range within specified limits. These units can be re-ranged in the field or instrument shop with hand-held communication tools and/or pressure standards. To select the appropriate model, determine the pressure range of the media being measured, identify the temperature of the media being measured, understand the corrosive nature of the media, and consider the mounting of the unit for practical installation, calibration and maintenance of the unit.

The working principle of level transmitters mentioned above varies according to their underlying principle. For instance, capacitance level transmitters operate through a capacitor, hydrostatic level transmitters depend on the pressure of a fluid in a storage container for level measurement, while ultrasonic level transmitters convert the distance travelled by an ultrasonic wave to determine the level, and so on. However, all these level transmitters measure the level in either of the three ways:

  • The weight of the fluid

  • The pressure head of the fluid

  • The position of the fluid in a container

 If you look closely, all the pressure transmitters covered in this post take into account either of the three factors to give an appropriate measurement. Level measurements are classified into two types– direct and indirect level measurements or performed by contact or non-contact transmitters. Direct level measurements are considered ideal for small level changes, which are observed in various industrial tanks. However, most level transmitters are designed for indirect level measurements as they are sensitive and designed for too high or too low level measurements, where direct measurement becomes difficult. Ultrasonic level transmitters can be availed in contact- or non-contact configurations.

Flange mounted level transmitters application

Flange mounted level transmitters may be installed directly onto a tank flange and are offered with a variety of tank connections. Typical applications include high-accuracy level measurement in pressurized and unpressurized vessels in the chemical and hydrocarbon industries.
