I laser distance meters RODER provide highly accurate and reliable level measurement with pinpoint accuracy and fast response times, ideal for silo and tank level measurement.

Laser distance meters are easy to install, they do not require recalibration and require minimal maintenance over their lifetime.

The non-contact nature of the laser sensor eliminates potential safety or contamination issues associated with the measurement of liquids in tanks, due to contact measurement methods.

The flexibility of laser distance meters allows them to be used in a variety of applications, such as the monitoring of liquid level changes in large storage tanks or identifying blockages or blockages in pipelines, as well as providing continuous level readings from multiple points simultaneously.

The ability to measure distances up to 100m makes them suitable for large warehouses where more traditional level sensors may not be usable due to the limitations of their range.

Laser distance meters they are able to measure horizontal and vertical distances without the need for direct contact or line-of-sight access, making them ideal for hard-to-reach places or awkward locations within silos and tanks.

They are extremely affordable compared to other non-contact sensors - they can be purchased at a lower cost compared to traditional ultrasonic level sensors or radar systems which require additional hardware and cabling costs.

Rated to IP65, these laser distance meters can be used outdoors even when exposed to rain, snow and other extreme environmental conditions (with suitable enclosures), allowing for greater flexibility during installation and operation in a range of applications within industrial plants and mining operations where robustness is essential in extreme external conditions (contact our technical support for more information).

By allowing remote control via a digital input/output connection configuration, operations can be controlled from a safe distance which reduces risk factors particularly related to personnel entering confined spaces such as manholes/pits, etc.

Measuring the liquid level inside a tank, silo or large container has never been easier thanks to the RODER LDM-42 laser distance meters. These precision instruments not only measure accurately and reliably, but also display real-time data on remote monitors via Ethernet or Wi-Fi.

RODER LDM42 laser distance meters open up new possibilities for monitoring the amount of liquid stored, so you know exactly when it's time to replenish and maintain inventory levels with confidence.

RODER's LDM42 laser distance meters are the perfect tool for measuring levels in silos and tanks. They offer unmatched accuracy and reliability, with readings consistently accurate to within 1 millimetre.

Data is displayed in real time on remote monitors via Wi-Fi or Ethernet networks, so you don't need to be on site to get up-to-date readings. The data also allows for tracking of inventory levels, so that when it's time to restock, you can be sure you have the right amount on hand.

Another advantage of using RODER LDM-42 laser distance meters is the ease of installation and operation. The meters can be easily mounted to the walls of tanks or silos, and the setup process is simple enough that anyone can do it.

Operation is completely non-contact, so no maintenance is required, other than occasional checks as needed. This makes them an effective choice for both large-scale industrial applications and small installations.

With RODER laser distance meters, even environmental factors such as temperature changes do not affect the readings, as they use retroreflective optical technology. This means that regardless of the extreme conditions, theAccuracy remains constant over long periods of time, with minimal effort on the part of the user.

Last but not least, having access to up-to-date information on the liquid content inside a tank or silo can be invaluable for any process dealing with liquid products: knowing exactly when it is time to order new stocks will save you money and time in the long run and help you stay ahead of your competitors by keeping your warehouses regularly stocked. RODER's LASER distance meters make all of this possible and reliable thanks to their advanced technological capabilities!

Thanks to its unique design and features, the LDM42 laser distance meter maximizes safety in tank level measurement applications. Eliminate manual checking processes that can be dangerous and time consuming. Since it does not require contact with any product, it helps to reduce hazardous conditions in the workplace.
