The differential pressure transmitter for high static pressure measures the differential pressure of a multiphase flow measurement system using a primary element. This high-precision sensor is designed to withstand the high static pressures resulting from the drilling depth of subsea wells. It withstands the extreme conditions of the marine environment and accurately measures water, oil and gas flows in topside drilling and offshore subsea production systems.
Since 1996, Fuji Electric France has been developing specific high static differential pressure transmitter for oil & gas applications and which is ideally suited to Topside and Subsea applications (depths down to 3500 meters).
Thanks to cutting-edge technology based on a sensitive sensor which floats in the neck of the cell, our differential pressure transmitters enable flow measurements with the suitable static pressures:
Inaccuracy and poor stability of differential pressure and flow measurement can lead to a huge loss of money or even to an equipment catastrophic failure. Under extreme static pressures, having an acceptable accuracy and reliability on the long run is a challenge for most operators that has been solved and improved by Fuji Electric since 1996.
Our pressure measurements are used by most international and national oil companies worldwide.
For these different types of applications, the pressure transmitter is designed for harsh production conditions and that can withstand static pressures up to 20,000 psi with low measured pressures.
Since 2020, hydrogen production projects (whether grey, blue or green) as well as new stations are booming. Hydrogen very low density in its gaseous state impose engineers to set an enormous compression factor leading to static pressures up to 1,379 barg (20,000 psig).
Benefitting from its experience in the Oil&Gas industry Fuji Electric supply its high static differential pressure transmitter with gold coating for hydrogen pressure and flow metering applications.
Thanks to the technology based on a sensitive element which floats in the neck of the cell, as well as the presence of a protection membrane, Fuji Electric high static pressure transmitter is able to achieve outstanding performances for severe environmental conditions unmatched by the competition.
Our transmitters are offered with a multitude of different process connections like a coned and threaded direct connection, or with or without remote seals, and are fitted with adequate marine offshore protection.

In a fast pace environment such as Subsea market, Single/Multi-phase Flowmeter Manufacturers need to focus on their core skills, as lead time reduction as well as standardization have become the standard. For high static pressures, to measure differential pressures in a consistent fashion has also been the one of the key to ultra-deep water flow measurement.
Since 1996, Fuji Electric has partnered with major OEMs (Original Equipment Manufacturer) customers in the oil & gas sector to design and manufacture integrated transmitter based on its differential pressure cell unrivaled performances. Oil operators being now forced to dig into new depths, our company is a partner of choice for flow meter manufacturers.
Our vertical integration in Clermont Ferrand (France) allows our company to co-engineer combined pressure transmitters with hyperbaric subsea hermetic design enclosures that have been supplied to all fields on the world.
