Product Description
The Sommer Messtechnik HSR-10 is designed for mobile and spontaneous flow velocity measurements in open water applications. Because it uses a contact-free radar method, the instrument avoids sensor fouling, reduces maintenance, and improves operator safety when measuring in difficult field conditions. It is especially useful for hydrologists, water agencies, emergency response teams, and field technicians who need rapid spot measurements without installing permanent equipment. Detects surface flow velocity using the Doppler frequency shift principle and displays readings in real time on an Android phone. Its portability, long battery life, and compatibility with the Makita 18V battery ecosystem make it a practical choice for extended field work and remote measurement campaigns.

What is the HSR-10 used for?
The HSR-10 is a handheld non-contact radar used to measure surface water velocity in rivers, streams, and open channels. It is designed for mobile field use and fast spot measurements without contacting the water.How does the HSR-10 measure flow velocity?
The HSR-10 uses Doppler radar technology to measure surface velocity by analyzing the frequency shift of radar waves reflected from the moving water surface.What are the benefits of a non-contact radar velocity meter?
A non-contact radar velocity meter allows safe measurements from above the water surface, reduces maintenance, avoids sensor fouling, and is ideal for difficult-to-access, high-velocity, or turbulent flow conditions.What is the measurement range of the HSR-10?
The HSR-10 offers a practical velocity range of 0.08 to 16 m/s and a technical range of 0.01 to 20 m/s, depending on water surface conditions.How accurate is the HSR-10 radar velocity meter?
The HSR-10 provides accuracy of ±0.01 m/s with ±1% full scale and a resolution of 1 mm/s.How long does a measurement take?
A typical HSR-10 measurement takes about 10 seconds, making it a fast solution for field velocity checks.How is the HSR-10 connected for viewing measurements?
The HSR-10 transmits data wirelessly via Wi-Fi and works with the HSR-Commander mobile app for setup, connection, and viewing measurement results.What comes with the HSR-10 bundle?
The HSR-10 bundle includes the handheld radar unit, a charger for Makita batteries, and a carrying case. Batteries are sold separately.What applications is the HSR-10 ideal for?
The HSR-10 is ideal for river studies, stream gauging, open channel flow checks, field inspections, and other mobile surface velocity measurement applications where fast, non-contact readings are needed.Does the HSR-10 require contact with the water?
No. The HSR-10 is a non-contact radar instrument, so it measures surface velocity without being submerged or touching the water.I can also make this more SEO-aggressive for terms like handheld radar flow meter, surface water velocity meter, and open channel flow measurement.
