Why Use a Data Transmitter?

A transmitter converts a physical tank measurement, such as level, temperature, or interface, into a standardized electrical or digital signal that can be used by control systems, inventory software, and safety systems. While gauges and sensors measure what is happening in the tank, the transmitter makes that information usable across the facility.
In storage tank applications, transmitters ensure measurements are consistent, repeatable, and accessible beyond the tank itself. They are the essential connection between field instruments and the systems operators rely on to manage inventory, prevent overfills, and maintain compliance.

In What Applications and Use Cases is a Transmitter Used?

Transmitters are used anywhere tank data must be monitored, recorded, or acted upon remotely. Common applications include:
Tank farm inventory management and terminal automation.
Custody transfer and inventory reconciliation.
Overfill prevention and alarm systems.
Integration with PLCs, DCS, and SCADA platforms.
Remote monitoring of unmanned or distributed sites.
Retrofitting mechanical or legacy gauges with digital outputs.
They are especially valuable in mixed tank farms where radar, servo, float & tape, and temperature devices must operate together on a common data network.

Why is It Important to Add a Transmitter to Your Level Measurement Package?

Adding a transmitter transforms a local measurement into actionable information. Operators gain real-time visibility, engineers gain reliable data for automation and reporting, and safety systems gain dependable signals for alarms and shutdown logic. Without a transmitter, critical tank information remains isolated at the gauge.

In modern storage facilities, transmitters are essential for scalability, interoperability, and long-term system value, whether supporting basic monitoring today or enabling advanced automation and digitalization in the future.

Data Transmitters: Turning Tank Measurements Into Actionable Information

Data transmitters serve as the bridge between tank-side instrumentation and facility-wide systems. They receive inputs from level gauges, float & tape systems, temperature probes, and auxiliary sensors, then convert those measurements into standardized analog and digital outputs such as 4–20 mA, HART, Modbus, or tank-gauging protocols. This allows tank data to be reliably shared with control systems, inventory management software, and safety logic.
L&J and Varec transmitters are purpose-built for storage tank environments. They use high-accuracy encoders, robust signal conditioning, and industrial-grade electronics to maintain measurement integrity over long cable runs and in electrically noisy tank farms. Many models support multiple inputs, including temperature and auxiliary devices, so a single transmitter can deliver level, temperature, interface, and diagnostic data from one tank.
Installation is flexible and retrofit-friendly. Transmitters can mount directly to mechanical gauges, integrate with radar and servo systems, or operate as standalone signal hubs. Hazardous-area approvals, galvanic isolation, and rugged enclosures ensure reliable operation in classified locations and harsh outdoor conditions.
Cognesense transmitters stand apart by offering deep, native compatibility across L&J and Varec measurement technologies. Designed as part of a unified tank-gauging ecosystem, they simplify integration, reduce commissioning time, and provide a future-ready foundation for accurate inventory management, overfill protection, and digital tank operations.
