The MB Bronze Messenger is a cornerstone of aquatic sampling engineering, acting as the vital link between the researcher and the submerged equipment. Designed to slide with precision along the main line, its function is to unfailingly activate the closing mechanisms of plankton nets, oceanographic bottles, and Ekman grabs. Manufactured from high-density bronze, this device ensures a steady descent and effective impact, allowing the capture of underwater nature to occur at the exact moment and depth required, protecting the purity of every collected sample.

The Mechanical Flow Meter with back-run stop is a specialized precision instrument designed for the most demanding oceanographic and limnological research. Its primary application is the accurate determination of the volume of water passing through a plankton net, although its robust design also makes it ideal for stationary monitoring in rivers and outfalls. By utilizing a three-blade impeller directly coupled to a non-resetting five-digit counter, the device provides a reliable mechanical record of every revolution during deployment.
Engineered for vertical operations, the "back-run stop" feature is critical for maintaining sample integrity, as it prevents the counter from registering reverse movements that could skew results. Constructed from a high-performance combination of plastic and titanium, the flow meter offers exceptional durability and corrosion resistance in aquatic environments. With a constant hydraulic pitch of 0.3 meters per revolution, researchers can easily convert mechanical counts into precise towing distances and volumetric data, ensuring that every expedition yields high-quality scientific evidence.

Use in rivers, estuaries, canals, sewer outfalls, pipes, and harbor entrances to determine velocity and distance information or use with plankton nets to determine water volume associated with each tow. Both models incorporate precision molded rotors coupled directly to six digit counters which record each rotor revolution. Supplied with a standard calibration curve (number of counts/unit time vs. velocity) sealed inside transparent body. A single pin and lanyard system located ahead of the lateral center of mass allows the flowmeter to maintain correct dynamic alignment with the fluid flow in which it is immersed. The ref. 2030R6 with a rotor of 7 in, is ideal for slow water (6 to 100 cm/sec) and ref. 2030R with a rotor of 3 in, is ideal for faster water (10 to 790 cm/sec).
Available extension handle for use of mechanical flowmeters in streams and moving water. 8 feet extends up to measure the flow of current hard to reach. Sold separately.
