AnyWare™ is an internet based fuel management software package designed to provide you with unparalleled monitoring and control capabilities of you fuel tank gauge. Residing on a local server in your home office, System Sentinel AnyWare™ will allow your personnel to access site information through any web browser. System Sentinel AnyWare™ accumulates valuable fuel management data from all of your sites into one location. The new export feature allows you to extract this data in several different formats so it can be used by other applications. The data files can be automatically sent to an email address, FTP site, or saved to a local drive. From there they can be easily incorporated into other business tools like accounting or fuel dispatch applications. The powerful rules engine of the System Sentinel AnyWare™ software package allows you to manage by exception through automatic forwarding of alarm, leak test and inventory information to the appropriate people when immediate attention is required.

​  Fuel Tank Gauges and Alarms

With simplicity in mind, the OLE Z2000 - Z5020 system can be installed in less than 1 hour. Installation of the sensor into storage tank then wired to display and mounted on a wall or pipe. Plug in the lap top for configuration and test the alarms and scroll screen.


There are 4 Software settable Level outputs M,1,2 & 3. High Alarm is connected to Master “M” These are FET’s providing supply voltage output when switched, so 12 or 24 vdc outputs. Optional Plug on Relays make these Volt Free connections. Additional flashing lights or control functions are optional, as are Bund and Water bottom alarms on the T4020-1A and T5020-1A range.  


Single or Multiple Tank gauging for any liquid or solid. Gasoil, Diesel, AdBlue, Lube Oil, Water, Ink, Molasses. Any tank shape can be programmed in this system. Safe area or EexiaIIc, Atex Zone 0/1 can be accommodated. IP 65 weatherproof, zone 2 / safe area . For Eexia applications barriers and IS sensors are provided. Display enclosure are RoHS & CE compliant.  

OLE ​​Z2000 & Z5020 ATEX Storage Tank Gauge

remote monitoring gauging system

The DTA 10 electro-pneumatic tank contents indicator consists of a battery-operated control unit with digital display and a measuring capilliary tube.
Measurements are requested by means of pressing the control key (Push-to-Read function) and If the level falls below a minimum level that is freely adjustable as a percentage, the back light of the display flashes red to indicate an alarm during the measurement. Standard tank shapes (linear, spherical, cylindrical and horizontal) are stored. Measuring line connection for hose with 4 mm inside diameter and universal application in storage tanks of up to a height of 4 m with the Density adjustable from 0.5 to 1.5 g/cm3, i.e. suitable for many liquids.
