Meets API Standards
The 4532 ATC is installed vertically onto spheres, bullets, cone, dome or floating roof tanks. Measurements are based on API (American Petroleum Institute) Manual of Petroleum Measurement Standard, Chapter 7.
Liquid and Vapor Profiles
The 4532 ATC contains up to 6 temperature elements, spaced at 2 or 3 meter intervals along the length of the probe. A continuous measurement profile of average liquid and/or average vapor temperature throughout the tank is available by reading the position and temperature of each element.
Tank Gauging System
Power and local HART communications are provided over a 2-wire, intrinsically safe (i.s.) connection from compatible instruments, such as the Varec 6005 Servo Tank Gauge (STG), 4560 Servo Gauge Monitor (SGM) or the 4590 Tank Side Monitor (TSM).
2-6 Platinum (Pt. 100), Class A element, multi spot configuration with a fixed interval of 6 to 9 feet, (2 or 3 meters) per IEC PUB 751 1995
