This section provides an introduction to the range of gauge boards produced and designed by Shelley with the scrolling banner, above, providing a range of examples. We work in Glass Reinforced Plastic which is tough, robust and easy to clean.
Shelley produce a range of standard designs, although special and adapted gauges can be designed on request. The gauge board PDF, available for download, gives illustrations of the standard design.
Inland Design Gauge Boards
- D50 design – An inland design gauge board, 145 mm wide and produced in 1 metre sections. Available with red datum metre numerals, if more than 1 metre is measured.
- D64 design – An inland design board, 100 mm wide and produced in 1 metre sections. Available with red datum numerals, if more than 1 metre is measured.
- D50 and D64 – Both are commonly used in rivers and reservoirs and comply with British Standard 3680 : Part 7 : 1971, Part 7, Methods of Measurement of Liquid Flow in Open Channels.
Tidal Design Gauge Boards
- D53 design – A tidal board designed for docks, harbours and marinas. It is 300 mm wide and produced in 1 metre sections.
Imperial Design Gauge Boards
- Imperial Boards – Fairly infrequently commissioned, but still asked for. The imperial board is 6 inches wide and produced in sections 3 feet long.
Special Design Gauge Boards.
Gauge boards can be produced as special designs to suit. Examples include:
- Colours – Gauge boards can be colour-coded, to improve interpretation. Or a background colour or edging can be used to highlight certain features.
- Infra-red colours – Experience suggests that white print on a black background is easier to read by people using infra-red cameras.
- Size – Wider or narrower gauge boards to suit location or reading distances
- Incline – Gauge boards often need to be produced as ‘incline boards’, because they are placed on a sloping surface. This means the digits need to be stretched, to reflect the angle of incline.
Standard gauge boards are produced as encapsulated Glass Reinforced Plastic prints. They are 4 mm thick, drilled, and are normally supplied with stainless steel screws. GRP is tried and tested. It gives a tough and robust product, and is suitable for long-term immersion in water.
PVC backing boards are available in either 1.5 or 3.0 metre sections [as a stock item]. These are intended to be a support, not a post system. Timber or galvanised steel posts, together with suitable fixings, can be quoted on request.
