Honeywell Tanksystem’s Onecal has been designed with users’ needs in mind. The cable, sensor and electronic display unit components can be changed without special tools or soldering. Recalibration is achieved by a simple ice point check that is easy to carry out without sending the unit to a laboratory, and without the need for a reference thermometer. Only the annual calibration verification, required by national standards, has to be performed against certified traceable reference thermometers. This translates into significant savings in transportation and repair costs, and a high degree of operational readiness.
Accurate temperature measurement is very important for volume calculation. This has been recognized by the international ISO 4268 standard (2000) and the American Petroleum Institute (API) Manual of Petroleum Measurement Standards (MPMS) Chapter 7 (2001). Honeywell’s Onecal helps users measure temperature accurately for spot-on volume calculation.
