The pressure gauge syphon is specifically designed to protect a pressure sensor from high-temperature media, for instance, steam. Other than that, it has also proven its efficacy by reducing the damaging possibilities of the pressure gauge in rapid pressure changes. The use of the symphony with the pressure gauge permits the system builders to use pressure sensors with a considerably lower temperature range in high-temperature applications too.

During the application, the syphon should be filled with water or analogous separating medium and the concentration of the pressure medium accumulated inside the coiled portion of the syphon helps abate straight contact with the external media and hence protect the pressure sensor


Compact Design – acquires less space for installation

Steam Protection – Generates a condensate barrier between the live steam process line and the pressure measurement

Freeze Protection – Develops a barrier to prevent freezing of instruments on wet air lines when the gauge syphon is filled with glycol. And to protect from freezing, kerosene is used.

Immediate Installation – No requirement of instruments for installation saves time

Gauge Whip Protection – diminish gauge whip by removing longer pigtail, permits close coupling to the respective process.


It is a well-known fact that the pressure gauge syphon is used to measure the pressure of liquid or gases in the industrial process system and therefore it is an indispensable part of the miscellaneous industries to prevent any hazard in the processing system. However, this pressure gauge gets damaged while subject to heavy loading or temperature and can permanently damage the measuring instrument.

Dynamic load cycles often result from pressure surges from a pump, which are visible on pressure gauges as pointer fluctuations. This dynamic load causes stress on the pressure element and all other mechanical components are also highly stressed due to the same, such a drastic fluctuation in the load perhaps reduces the life of the pressure gauge. This diverse impact of the load cycle needs to be addressed to increase the lifeline of the pressure gauge either by additional fittings or by equipping pressure ports during the pressure gauge syphon manufacturing. However, the extra fitting rather than the inbuilt gives a higher level of versatility and therefore it is preferable globally.

Such extra fittings are reckoned as a pressure gauge syphon in industries that not only protects pressure gauges from high pressure but also from high temperatures. Therefore, syphon or compact syphon is worth considering for protecting pressure gauge and other parallel instruments from the hot media, and vapors along with load cycles and ensuring the highest level of reliability and surety.

What are the types of pressure gauge Syphon?

The pressure gauge syphon are mainly available in three types sequentially, coil syphon, pigtail syphon and U Type syphon and each is designed to match different application requirements of the industries using a pressure gauge.

Coil Syphon – used primarily for horizontal installations

The coil shaped design is a reason for its recognition as a coil syphon, which are extensively celebrated in the industries for its effectiveness in preventing pressure gauge from the effect of hot pressure media and reducing the effect of quick pressure surges. This coil syphon permits the formation of condensate that gathered inside the syphon and hence prevents direct contact of hot media with the pressure instruments. The excellent command of this coil syphon has made it widely popular as freeze protector.

Special Features

Coil syphons are used significantly to protect pressure instruments, pressure gauge syphon, switches and transmitters straightly contacting with high temperature process fluids or vapours. This coil syphon is installed between process and pressure instruments and filled with condensation fluids that reduce process pulsation and function as heat dispensed and save instrument from working at unsafe temperatures.

Pig tail Syphon – Used primarily for vertical installations

The pigtail syphon is a looped pipe filled with water, designed profoundly to guard the internal parts of the steam pressure gauges against an elevated steam temperature. It is also one of the highly sensitive measuring instruments that demand significant caution in order to prevent damage or destruction. This pigtail pressure gauge syphon permits the change of gas into a liquid by dissolving the hidden heat energy of steam and permitting steam to condense, thus developing a loop seal of liquid that puts off the conveyance of heat energy from the steam to the respective gauge. This pigtail syphon is well-liked in the market for its impeccable operation and reliability measures that are also widely accepted to protect the steam pressure gauge from any pressure surges in the system. During the application, it is recommended to fill the pigtail syphon with water or another parallel liquid substance.

Special Features:

The pigtail syphon is installed between process and process instruments in order to protect the measuring instruments, including pressure instruments, gauges, switches, and transmitters, from entering high-temperature process vapors. Other than that, this pigtail syphon is known to be effective in preventing the instrument from working at hazardous temperatures. This pigtail syphon is prominent in the industry for its influential functioning throughout its life and for ensuring the safety of the respective instrument.

U Type Syphon – Used primarily for horizontal installations

The U shape of the pipe connected between the pressure gauge and process makes it renowned as the U type syphon in the industries. This U type Syphon is globally accepted for its outstanding performance, used widely to prevent the entering of hot media into the measuring instrument hence protect the instrument from the damage. This U types syphon permits condensate to form and be accumulated inside the syphon that prevents direct contacting of the hot vapors with the pressure instrument. However, it is counseled filling the U type syphon together with a cooling separating liquid ahead of starting the pressure line. This U type syphon is also being prominent in the heating dispersion that prevents instrument to work at hazardous temperature.

Special Features:

The U type syphon is equipped between process and process instruments to ensure safety of the pressure instruments, gauges, switches and transmitter from the entering high temperature vapor. This U type syphon intensifying popularity in the diverse industries is an evidence of its worthiness, which is also being used to avoid instrument to work at dangerous temperature.
