The 139M Servo Gauge is an intelligent, microprocessor based instrument for accurate measurement of product level, interface level, density & temperature. It is used for custody transfer & inventory control applications & meet the requirements according to OIML R85 & is SIL2 certified (Functional Safety) for overfill protection applications in hazardous locations.
A Float & Tape type Level Gauge for level measurement of clear liquids in large bulk storage tanks - Cone Roof, Floating Roof, Underground, Reservoirs & Sumps, etc. The use of a large diameter float & constant force spring ensures high accuracy & reliability.
Available to be fitted with the 133 ATLG, the 133 TS offers a 4-20 mA DC output to provide remote indication of level and a limit switch whose contacts are used for alarm annunciation or remote control applications.
Designed to fitted/retrofitted with the 133 ATLG, It is a microprocessor based transmitter for accurate digital conversion and transmission of product level and temperature data of tanks on a multi-drop RS 485 bus. It also provides an optional temperature measurement using an external temperature sensor SBEM’s 133 TMP.
The Communication Interface Unit (CIU) is an intelligent control room instrument and is used for interfacing field transmitters to a server PC in the control room loaded with SBEM Tank Inventory Management Software (SBTIS), to form a complete tank inventory management system. The CIU is also available in a hot swappable redundant configuration for reduced down time.
An accessory to STDT + ATLG / Servo Gauge (SG) for real time average temperature measurement of liquid and vapour phases of the product. Averaging Temperature Sensors with Pt-100 elements (multi-point) are housed in sealed SS hose and are supplied complete with mounting accessories.
A Windows based software package for calculation of inventories at standard temperature by volume or by mass. A menu driven and user friendly navigator provides inventory reports - tank wise, product wise, group wise and in various formats. Data logging, file transfers, networking and interfacing/integrating with supervisory system e.g. DCS, SCADA, LRC, PLC, etc. is possible.
