2500 Automatic Tank Gauge

2500 Automatic Tank Gauge

The 2500 Automatic Tank Gauge (ATG) is a mechanically operated, float & tape instrument designed to provide continuous liquid level measurement in bulk storage applications. This simple and reliable instrument has been used for managing inventory in the oil and gas industry for the past 90 years.

Meets API Standards

 

The 2500 ATG meets API Chapter 3.1B regulations for inventory control applications with a measurement accuracy of 0.2” (4 mm). It’s also built in the USA to 3rd-party quality assurance standards, and is ATEX approved for use in potentially explosive atmospheres.

 

 

Easy-to-Read Display

The measured level is displayed at the tank side using a dial and counter built into the gaugehead. Varec pioneered the technology 90 years ago and it has proven itself ever since, probably due to it’s simplicity and reliability – just ask anyone in the industry.

 

 

On Your Tank

Select the installation kit suitable for your bulk liquid storage tank. Floats are available for standard, interface or stilling well applications. If you have one of our competitors gauges we can easily upgrade the gaugehead, float, and tape, without replacing the hard-mounted tank fittings.

 

 

Data in the Control Room

If electronic transmission of level data or temperature measurement integration is required in the control room, then the gauge can be fitted with an optional tank gauging transmitter. Varec’s new 2920 FTT offers tank side viewing and configuration using a touch screen display.

 

 

 

Optimize Performance

If it’s time to replace your negator motor, consider upgrading to a Negator Cassette. The cassette optimizes the performance of your gauge by reducing friction for smoother operation. It also reduces maintenance and extends the working life of the gauge by protecting the motor from contaminants that may enter the gaugehead.

 

 

Training and Support

The 2500 ATG, its accessories, and it’s spare parts are available to ship today. Every part is supplied with detailed user instructions, but sometimes you need to see how it’s done. That’s why we also have a YouTube channel with basic how-to-videos. If you need direct support, we offer standard training and service programs that we tailor to your staff, and your facility.
