Rotogages® are designed to provide accurate determination of LP-Gas container contents. They may be end or side mounted in a standard 3/4" NPT coupling on stationary or mobile containers. To guarantee accurate measurement, they should not be used on stationary containers that exceed 60" I.D. or on mobile containers, subject to vibration, with an I.D. of more than 24".
Rotogages® are designed to provide an accurate determination of LP-Gas or anhydrous ammonia container contents. They mount in a standard 1" NPT coupling on large mobile or stationary containers.
To operate the Rotogages®, the vent valve is opened and the dip tube rotated slowly from the container vapor space to the liquid space. The difference in appearance of the discharge indicates when the liquid level is reached. Dial readings then indicate the percentage of product in the container.
The RTC 3960 gauge measures the level in Liquefied Petroleum Gas (LPG) or Liquefied Natural Gas (LNG) tanks using a 4-inch still-pipe as a waveguide. It gives high reliability with no moving parts and no contact with the liquid. All electronics are housed in the explosion-proof housing, located outside the tank. Reference devices make it possible to verify measurements without opening the tank - no need for expensive calibration chambers and large-size valves.
The still-pipe ensures a sufficiently strong echo even under surface boiling and turbulent conditions.
The gauge uses state-of-the-art Frequency Modulated Continuous Wave (FMCW) radar technology. For highest measuring accuracy the gauge can be equipped with a pressure sensor for calculation of vapor content.
The 3960 has inputs for temperature sensors, HART® based pressure sensors and other analog inputs as well as analog and relay outputs. All data is transmitted on the two-wire TRL/2 field bus. As an option the gauge can be equipped with other output buses such as Foundation™ fieldbus Profibus DP or Tiway. It can also emulate other vendor's buses when installed in existing tank gauging systems.
Designed for high pressure use
The pressure seal is a quarts window approved for use in pressure vessels up to 25 bars (365 psig). The gauge has an optional fire proof block valve and a vapor pressure sensor.
Raptor really takes tank gauging to another level, making you better equipped to handle the ever-increasing demands on efficiency, safety and accuracy. It is a complete and flexible tank gauging system, based on the open industry standard FOUNDATION™ fieldbus. Raptor can be used for refineries, tank terminals and in the petrochemical industry. It is the accurate system for custody transfer, process control, inventory control or for filling a tank without risk of overflow. The system can be designed for SIL 3 safety. The system includes cost-effective alternatives for each performance class. It can be configured with:
