Advantages of Wema Products

Wema has earned its reputation by consistently delivering quality and reliability. Here are some of the standout benefits of choosing Wema for your boat’s gauges and sensors:

• Precision & Reliability: Wema gauges and senders provide accurate readings you can count on. They are widely used in marine (and even automotive) industries for monitoring tank levels with proven precision and reliability, ensuring you always know the status of your fuel, water or waste tanks.
• Marine-Grade Durability: Built to withstand harsh marine conditions, Wema products use stainless steel and other non-corrosive materials. Many Wema gauges are waterproof (rated up to IP56 or higher) with single-skin anti-fog coated lenses, so your dials stay clear and functional in all weather.
• Standards Compliant: Wema’s sensors are constructed to meet strict international standards, including ISO, CE, NMMA, ABYC, and USCG requirements. This compliance means they meet or exceed marine industry regulations for safety and quality, giving you peace of mind on the water.
• Easy Installation: Installing Wema products is typically straightforward. Their senders often use the standard SAE 5-hole tank flange pattern, and gauges come in common dash sizes, making it easy to swap out old equipment. In many cases, fitting a Wema sender is as simple as mounting it and connecting two wires to your gauge – perfect for DIY boat owners.
• Compatibility & Versatility: Wema gauges and sensors are designed to work with a variety of boat systems. Most gauges operate on 12V by default but include resistors or design features to support 24V systems as well. Likewise, Wema tank senders are available in different resistance ranges (e.g. 240–33 Ω or 10–180 Ω), so you can pair them with existing gauges from Wema or other brands. This versatility makes it easy to integrate Wema products into virtually any marine setup.
• Custom Fit Solutions: With Wema, you’re not stuck with one-size-fits-all. They offer sensors in various lengths and configurations to suit different tank sizes and shapes, and they’re known for tailoring fuel and water tank sensors to any specification – no matter your tank form, hull size, or mounting hole pattern. This means you can find a Wema sender or gauge that fits your boat perfectly, or even have confidence that OEMs trust Wema for custom applications.
   

How to Choose the Right Wema Product

Choosing the right Wema gauge or sensor is all about matching the product to the function you need on your boat. Consider what system or measurement is most important for you, then select a Wema product designed for that purpose. Here are a few examples to guide you:

• Speed Monitoring: If you want to track your boat’s speed without relying on a pitot tube or paddle wheel, a GPS-based speedometer is ideal. The Wema GPS Speedometer Black 60 Knots is a great choice – it uses GPS signals to give you accurate speed readings up to 60 knots. This means hassle-free installation (no through-hull sensors required) and reliable performance for sailors and powerboaters alike.
• Electrical System Health: To keep an eye on your battery and charging system, consider an ammeter gauge. The Wema Ampmeter Gauge Digital Black 12/24v provides a clear digital readout of your boat’s current (amps) in real time. It supports both 12V and 24V systems, so whether you have a small runabout or a larger cruiser, this gauge helps you monitor power usage and avoid electrical issues.
• Engine Performance: Monitoring your engine’s RPM is crucial for performance and longevity. The Wema Gasoline Tachometer Black 12/24v is designed for petrol engines, giving you an accurate reading of engine speed (revolutions per minute). With compatibility for 12V/24V systems, this tachometer ensures you can fine-tune throttle settings, prevent over-revving, and run your motor at optimal RPMs.
• Steering & Maneuvering: Knowing your rudder position at a glance can make docking and tight maneuvers much easier. Wema offers a comprehensive rudder angle indicator system – the Wema Rudder Angle Indicator Sender Dual Station works with a Wema Rudder Angle Indicator Gauge Black 12/24v to display your current rudder angle. This setup is perfect for boats with dual helm stations (e.g. flybridge and lower helm) because the sender can drive two gauges, so both steering positions always show the same, accurate rudder angle. It’s a must-have for precise navigation and control on the water.
   

FAQs – Frequently Asked Questions about Wema

Q: Are Wema gauges waterproof?
A: Yes – most Wema gauges come with marine-rated water resistance (often IP56 or higher) and anti-fog lenses, so they stay clear and dry even in harsh sea conditions.

Q: Can Wema gauges run on both 12-volt and 24-volt systems?
A: Absolutely. Many Wema gauges are 12V by default but include a resistor or are designed to support 24V as well. Always check the product details, but generally you can use Wema gauges on either 12V or 24V setups without issues.

Q: How do I choose the correct Wema fuel sender for my tank?
A: Measure the depth of your tank and choose a Wema sender that matches that length (Wema offers senders in various lengths to fit different tank sizes). Also ensure the sender’s resistance output matches your fuel gauge (for example, 240–33 Ω or 10–180 Ω) so that the readings will be accurate.

Q: Do Wema gauges come with the necessary sensors or senders included?
A: Not usually. In most cases, gauges and senders are sold separately – for instance, a Wema fuel gauge and a Wema fuel tank sender are two different items. This allows you to replace one without changing the other. Check each product description to see what’s included, and if you need a complete setup, make sure to purchase both the gauge and the corresponding sender.
