Tank Gauges & Senders
To accomodate the ever increasing demands of the modern yacht owner and builder IMP is proud to represet two leading manufacturers in San Giorgio S.E.I.N. and Tank Tender, that will offer all of our customers complete reliability, assurance and value for money in all tank readings whichever system or design you choose.
San Giorgio S.E.I.N.
San Giorgio S.E.I.N. was established in 1960 and was the first Italian company to produce electric and electronic teleindicators for the marine industry. Through continuous development of its products and technology, San Giorgio S.E.I.N is now the market leader in Italy supplying the Italian Navy, Coast Guard, Ferretti and Azimut Groups to name a few.

Compatibility with other leading the brands including VDO and WEMA for the replacement market is assured with the added benefits of increased quality, competitive pricing and customisation available.
The San Giorgio SEIN range of products are split into 3 product catalogues:
1. Professional range - for professional vessels, super yachts and classified yachts.
2. Seagull range - for medium to large sized vessels and where quality and VDO compatability is required.
3. SGS range - for small to medium sizes vessels where reliability, value and compatability with WEMA products is required.
Additionally many of their products are approved in accordance with strict
international standards and include: Gauges, Temperature and Pressure Sensors, Voltmeters & Ammeters, Engine Panels, Monitoring Systems and Electronic Instruments.
Tank Tender
Before Tank Tender you had to rely on an old-fashioned dip stick, site glass or electric float gauge to check the level of your boat's fuel, water or holding tank. Not anymore.

Tank Tender provides extremely accurate readings for up to ten tanks. Without electricity. Without leaving the bridge. Without a doubt.
Tank Tender operates on air pressure. Select the tank, then pump a small amount of air through tubing to the bottom of the tank. When the air pressure in the tube equals the liquid pressure at the bottom of the tank, the gauge displays this pressure in inches of liquid.
Tank Tender's features include:
- It's convenient. Monitor the levels in all tanks with just one instrument.
- It's easy to use. You can select a tank to measure and get an accurate measurement from the bridge in two or three seconds.
- It's simple to install. The average 4-tank system takes about an hour. And there's nothing to wire.
- It's surprisingly inexpensive. Tank Tender costs much less than other industrial systems offering similar accuracy and reliability, and only slightly more than conventional electric gauges.
