1/29/2024 0 Comments Water depth gauge![]() ![]() We have standard designs for 40 degree and 45 degree boards but most applications are bespoke and artwork is created to suit. Incline gauge boards are used where the bank or wall of the water course is at an angle. As illustrated in the photos below 3 size options are available. Gauges should be located in a clear position, with a good line of sight from both sides. They are designed for use at fords or roadside locations where flooding is a common problem. There are 3 design options for Ford & Flood gauge boards and all comply with the UK Traffic Signs Regulations. They read in reverse to show the clearance height. For clear and easy reading they are normally produced at 300mm wide with black text on a yellow background, although this colour scheme can easily be amended. Air Draught BoardsĪir draught boards are designed to clearly display the clearance heights under bridges, structures or in tunnels. When gauge boards are used in this application we recommend amending the style of the datum numeral to a ‘reversed’ out image as this example. This is highly visible for ambient light but works less well if the gauge boards are being monitored by infra-red cameras. The standard gauge board has black digits on a white background with datum or metre numerals printed in red on white. ![]() All our gauge boards can be produced with a Retroflective finish. The reflective surface reflects light back to the source of the illumination making them easy to read on dull days, when there is limited light or at night. Retroflective Gauge Boards work in a similar manner to standard road signs – they are easy to read and use with an appropriate light source (headlights, torch, spot light). All our gauge boards can be produced with this photoluminescent finish. This material self charges using ambient light and then glows, in the dark, strongly enough for the graduations to be clearly visible. Photoluminescent Gauge Boards are commonly known as ‘glow in the dark’ boards. This means the digits need to be stretched, to reflect the angle of incline. Incline – Gauge boards often need to be produced as ‘incline boards’, because they are placed on a sloping surface.Size – Wider or narrower gauge boards to suit location or reading distances.Infra-red colours – Experience suggests that white print on a black background is easier to read by people using infra-red cameras.Or a background colour or edging can be used to highlight certain features. Colours – Gauge boards can be colour-coded, to improve interpretation.Gauge boards can be produced as special designs to suit. The imperial board is 6 inches wide and produced in sections 3 feet long. Imperial Boards – Fairly infrequently commissioned, but still asked for. ![]() It is 300 mm wide and produced in 1 metre sections.
