--- title: "INTEGRA HLA: High Low Alarm System | Citia" description: "INTEGRA HLA is a high-low alarm system that raises high, high-high, low and low-low level alarms for each tank, on a local annunciator and in SCADA." url: https://citia-engineering.com/en/products/high-low-alarm language: en updated: 2026-11-11 type: product site: Citia Engineering Indonesia --- # INTEGRA HLA INTEGRA HLA is a high-low alarm system that raises high, high-high, low and low-low level alarms for each tank, on a local annunciator and in SCADA. | Field | Value | | --- | --- | | Family | INTEGRA | | Type | High Low Alarm System | | Status | Configured per facility | | Updated | 2026-11-11 | ## What it does INTEGRA HLA watches tank level limits from ATG data or independent level sensors. When a level crosses high, high-high, low or low-low, the operator gets an alarm on a local annunciator and in SCADA, so receipts, storage and loading stay within tank limits. Setpoints, measurement source and alarm response are set in a facility engineering review. ## Main functions - High and low limit alarms - High-high and low-low limits - Local and SCADA alarm display - Function checks and setpoint records ## Who it supports - Tank farm operators - Instrumentation and reliability teams ## Connects to - ATG / Level sensor - PLC / SCADA - Local annunciator ## Related solutions and products - [Tank farm & inventory](https://citia-engineering.com/en/solutions/tank-inventory.md) (solution) - [Control systems & instrumentation](https://citia-engineering.com/en/solutions/control-instrumentation.md) (solution) - [INTEGRA TAS](https://citia-engineering.com/en/products/terminal-automation-system.md): INTEGRA TAS is a terminal automation system that runs truck loading at fuel and LPG terminals, from order and gate-in to filling and gate-out documents. - [INTEGRA TMS](https://citia-engineering.com/en/products/tank-management-system.md): INTEGRA TMS is a tank management system that collects automatic tank gauge (ATG) readings for live levels, history, tank tickets and SAP stock posting. - [INTEGRA TPS Integration](https://citia-engineering.com/en/products/tps-integration.md): INTEGRA TPS Integration is a reporting application that prepares, submits and tracks receiving and delivery reports for Indonesian Customs (TPS Online). - [INTEGRA Weighing](https://citia-engineering.com/en/products/weighing-management.md): INTEGRA Weighing is a weighing management system that pairs weigh-in and weigh-out for each truck and issues the weigh ticket. - [INTEGRA Access](https://citia-engineering.com/en/products/access-control.md): INTEGRA Access is an access control system that decides who and which vehicles may enter each area and keeps a full entry and exit record. - [INTEGRA Fleet](https://citia-engineering.com/en/products/fleet-management.md): INTEGRA Fleet is a fleet management system that shows where each vehicle is, how its trip is going and what happened on the road. - [INTEGRA CTP](https://citia-engineering.com/en/products/connected-terminal-platform.md): INTEGRA CTP is terminal automation delivered as a cloud service, with gateways and edge software at each site. It is in development. - [ORSYNA](https://citia-engineering.com/en/products/orsyna.md): ORSYNA is an AI layer on INTEGRA TAS that finds tank tickets and operating history on request. It is in development and evaluation. ## Arrange a technical demo Show us your workflow and equipment. Citia walks through INTEGRA HLA with example data and maps what needs to connect.
