Water Level Depth Gauge Boards for Marine & Inland Applications
Depth gauge boards are manufactured to provide clear and accurate water level measurement across rivers, reservoirs, canals, locks, harbours and marine navigation environments.
Suitable for both inland and coastal applications, systems are available in standard primaDURA aluminium and photoluminescent primaDURA GLOW formats depending on operational and visibility requirements.
Manufactured using a 3mm encapsulated and stove-finished primaDURA aluminium process, depth gauge boards are engineered for long-term performance across harsh external and marine environments.
Systems provide strong resistance to UV exposure, saltwater, airborne contaminants, abrasion and impact, making them suitable for continuous outdoor use and prolonged water immersion.
NOVADURA depth gauge boards have demonstrated long-term durability across real-world marine environments, including installations operating for over 15 years in exposed coastal conditions.
primaDURA GLOW systems provide enhanced low-light visibility with extended afterglow performance to assist navigation and safety in reduced visibility conditions.
Photoluminescent systems are manufactured to PSPA Class D standards in accordance with:
- DIN 67510 Part 1
- ISO 16069
Products supplied to maritime environments can also include Lloyd’s Register certification and the “Ships Wheel” mark confirming compliance with Marine Equipment Directive and SOLAS requirements.
Designed for demanding environmental conditions, depth gauge boards typically provide an operational lifespan of approximately 20–25 years.
Depth gauge board systems are commonly specified for harbours, marinas, lock systems, coastal infrastructure and inland waterway applications requiring durable long-term environmental performance.
Standards & Compliance
Depth gauge boards are manufactured in accordance with recognised hydrometry, marine and photoluminescent performance standards including:
- BS EN ISO 4373:2008 Hydrometry: Water level measuring devices
- BS 3680 Part 7:2000 – Measurement of liquid flow in open channels
- PSPA Class D photoluminescent performance
- DIN 67510 Part 1 compliance
Systems can also be supplied for marine environments requiring SOLAS and Marine Equipment Directive compliance.
