EST4300 Smart Flange mounting Liquid Level Transmitters
EST4300 Differential Pressure Level Transmitter measures the level of liquids based on the principle of static pressure, which outputs analog or digital signal 4~20mA and is used for the liquid measurement in industrial process control and metering. With level mounting flanges, the Differential Pressure Level Transmitter can be mounted directly to the tank to be measured, and provide accurate measurement of the pressure, differential pressure and liquid level of various tanks.
EST4300 Differential Pressure Level Transmitter has two connection ways, direct mount and remote mount. Both connections are engineered to meet a wide variety of measurement needs.
- Direct mount connections offer simple installation for mounting transmitters directly to the vessel eliminating the need for additional transmitter mounting provisions.
- Remote mount connections consist of a seal attached to a transmitter via capillary tube and are used in tuned or balanced systems, high temperature installations and remote transmitter mounting applications
Differential pressure transmitter can be used for level measurement in most cases; however, a Flange Mounting Differential Pressure Level Transmitter is needed for any of the following situation below.
- Where the process liquids are prone to solidifying or crystallizing
- Where the process liquids are too thick or contains suspended solid
- Where the process liquids can easily block the impulse lines
- Where the process liquids are hot or corrosive, and cannot be measured directly
- Where the process liquids are food or other materials that cannot be contaminated
