These instruments have been the liquid level measurement technique of the petroleum tank gauging market for over 90 years due to their simplicity, reliability and cost.
Float and tape tank gauge LTD solution consists of a 2500 ATG selected for the appropriate tank type. The instrument provides a measurement to +/- 4 mm accuracy and tank side display that is suitable for inventory management to API specifications. If control room integration and volumetric calculations are required, a 2920 FTT tank gauge LTD transmitter is recommended with a 8500 STS for spot temperature measurement.
The selection of the transmitter often depends on the required or existing field communications and protocols. The 2500 ATG/2920 FTTcombination is ATEX approved and is also able to provide optional contact outputs for triggering alarms or relays. If only an analog (4…20 mA) level output is required (without temperature) the 8200 COT can be used.
