Veeder-Root EMR4 Electronic Meter Register
Description
Electronic register with retrofit kits for common fuel meter makes
The Veeder-Root EMR4 is an electronic meter register for fuel meters. A display head shows the delivered quantity on an anti-fog, nitrogen-purged, ultra-bright LED back-lit display, and an interconnect box (IB) connects display heads, pulsers, printers and solenoid valves. A system can have two display heads per interconnect box and up to 32 display heads (16 interconnect boxes) can be daisy-chained into one network, which can share a common printer.
The datasheet is a hardware list: it names display heads in English, French and Spanish, remote display heads, UL/cUL and ATEX/IECEx interconnect boxes, installation and retrofit kits for specific meter makes, remote pulser kits, the DataLink serial kit and accessories such as printers, temperature probes and valve kits.

The register is described in a separate EMR4 Application Guide (577014-339), which the datasheet references for power conditioning and system design.
What to confirm before ordering
- Meter make and model, to choose the installation or retrofit kit (Tokheim, Smith Meter, Neptune, Brooks and others are listed).
- Language of the display head, and fixed or remote display.
- Hazardous-area requirement: UL/cUL or ATEX/IECEx interconnect box and pulser kits.
- Whether temperature compensation, a printer or DataLink communication is required, and the legal-metrology approval (for example OIML R117) your authority needs.

About brand
Veeder-Root is an American supplier of automatic tank gauging and fuel management systems for service stations and fuel depots. The company was formed in May 1928 by the merger of Curtis Veeder's Hartford counter business, started in 1895, with the Root company of Bristol, Connecticut. A counter fitted to a gasoline pump in the early 1930s took Veeder-Root into the petroleum industry. Today it is part of Gilbarco Veeder-Root, a Vontier company.
Seven Star LLC is an independent supplier in Muscat. We list Veeder-Root consoles, probes and sensors from the maker's published datasheets for fuel stations, depots and airports in Oman and the GCC.

Veeder-Root product series
Tank gauge consoles include the TLS4 and the non-expandable TLS4B, the TLS-450PLUS and the legacy TLS-350PLUS. Mag Plus in-tank probes are offered for gasoline and diesel, jet fuel, LPG and light and heavy oil, and Mag-FLEX probes cover tall tanks. Leak detection sensors include the discriminating containment sump sensor 0794380-352 and the interstitial sensor 0794390-420 for double-wall steel tanks. The EMR4 electronic meter register is used on fuel delivery trucks.
Where Veeder-Root products are used
Petrol stations, fuel depots, airports and fleet fuelling sites, where the system measures product level, water and temperature in underground and aboveground tanks, monitors sumps and interstitial spaces and supports inventory reconciliation and leak tests.
