Detailed description

Designed for accurate monitoring of onboard tank levels, the BLUE SEA VSM 422 PN 1810 ultrasonic sensor is a technical solution dedicated to essential fluids. It is specifically adapted to diesel, freshwater, and wastewater tanks, distinguishing it from the PN 1811 model, which is reserved for gasoline tanks. This sensor features a technology with no moving parts, contributing to its long-term reliability by eliminating the risks of wear and mechanical failure commonly associated with traditional float sensors.

Precision and Technical Robustness

The VSM 422 PN 1810 offers a measurement accuracy of +/- 3.81mm (0.125"), a key advantage for rigorous management of consumables and discharges. Its design incorporates digital filtering to compensate for errors caused by sloshing of liquids in mobile tanks, ensuring stable readings even while underway. The device operates on a voltage range of 10 to 32 Volts DC and supports a maximum tank depth of 812.8mm (32.00"). Its operating temperature range extends from -40°C to 85°C, ensuring performance in various marine environmental conditions.

Installation and Compliance

The sensor is installed via a standard 5-bolt SAE flange, with a maximum torque of 1.7 N•m (15 in-lbs). It requires a 1-5/8" (41.3mm) hole for integration. The BLUE SEA VSM 422 PN 1810 is ignition-protected and has been tested according to ABYC H-24 standards for fuel system components, attesting to its compliance with maritime safety requirements. It must be connected directly to the vessel's main negative bus to avoid interference from high loads such as battery chargers, ensuring the stability and accuracy of readings. It is supplied with its sealing gasket, designed for precise alignment with electrical connections and mounting holes.

« Reliability of BLUE SEA ultrasonic tank monitoring »

The BLUE SEA VSM 422 PN 1810 ultrasonic sensor represents a significant improvement over traditional mechanical level probes, which are often prone to failure due to moving parts or fouling. Its ultrasonic technology ensures complete non-contact with the fluid, eliminating issues related to corrosion or failure linked to the tank environment. For sailboat or powerboat owners, this type of sensor provides enhanced reliability for monitoring diesel fuel, fresh water, and wastewater levels—critical data for voyage planning and onboard autonomy.

During installation, it is essential to follow placement guidelines: the sensor must be mounted at least 76.2mm (3.00") away from any bulkhead, partition, or dip tube to avoid parasitic sound reflections that could distort measurements. On irregularly shaped or conical tanks, it is recommended to position it on the deepest section to optimize accuracy. The three-wire wiring, with a 10-32V DC power supply, facilitates integration into most modern marine electrical systems. One key point is grounding: direct connection to the main negative bus is mandatory to ensure signal integrity and prevent interference from other current consumers. It is also important to note that if the sensor loses power, the VSM 422 monitor will display the tank as "full," which may have implications for high-level alarm systems.

This sensor is part of a complete monitoring solution with BLUE SEA’s VSM 422 system, offering a high-performance and durable alternative to float or resistance probes.

Frequently Asked Questions

Need help? Contact us

What type of technology is used by the BLUE SEA VSM 422 PN 1810 tank level sensor?

The BLUE SEA VSM 422 PN 1810 sensor uses ultrasonic technology. This design with no moving parts ensures increased reliability and eliminates the risks of wear or mechanical failure commonly associated with traditional float sensors.

Which types of fluids are compatible with the VSM 422 PN 1810 tank sensor?

The VSM 422 PN 1810 sensor is specifically designed for monitoring diesel, fresh water, and wastewater levels. It is not compatible with gasoline tanks, for which the PN 1811 model is required.

What is the measurement accuracy of the BLUE SEA VSM 422 PN 1810 level sensor?

The BLUE SEA VSM 422 PN 1810 sensor provides a measurement accuracy of +/- 3.81 mm (0.125"). It also features digital filtering to compensate for errors caused by liquid sloshing in mobile tanks, ensuring stable readings even while underway.

What is the maximum tank depth that the VSM 422 PN 1810 sensor can measure?

The BLUE SEA VSM 422 PN 1810 sensor can measure tanks up to a maximum depth of 812.8 mm (32.00").

What is the required mounting type for installing the BLUE SEA VSM 422 PN 1810 tank sensor?

The sensor is installed using a standard 5-bolt SAE flange. A 1-5/8" (41.3 mm) hole is required for integration into the tank. The maximum recommended bolt torque is 1.7 N•m (15 in-lbs).

What is the required supply voltage range for the VSM 422 PN 1810 tank sensor?

The VSM 422 PN 1810 sensor operates on a supply voltage range of 10 to 32 Volts DC. It requires an external power source and must be connected as directly as possible to the main negative bus of the boat's electrical system to avoid interference from high loads.

Are there specific recommendations for sensor placement inside the tank?

Yes. For optimal performance, the sensor must be located at least 76.2 mm (3.00") away from any side, baffle, dip tube, or other obstruction to avoid sound reflections. Ideally, it should be mounted on the deepest part of the tank if it is conical, or as close as possible to the center of the tank top if it is rectangular.

What is the warranty policy for the BLUE SEA VSM 422 PN 1810 tank sensor?

Blue Sea Systems offers a satisfaction guarantee. Any Blue Sea Systems product a customer is not satisfied with can be returned for a refund or replacement at any time.
