Current Meter

HyQuest Solutions’ Redback is a cup-type current meter for the measurement of water flow in open and closed waters to a fine degree of accuracy and repeatability. This is due to its advanced contact switching system and interchangeable bucket system that provides trouble free operation.


The Redback is made to be used in the most extreme environments and ensures reliable  field service for many years.


The current meter is supplied in a user-friendly kit, allowing the operator to measure water flow using a simple traditional method.



The advanced contact switching system of the Redback allows the measurement of water flow in streams, open canals, pipes, and seas to a fine degree of accuracy and repeatability.

Current Meter Counters (various models):

Features: waterproof enclosures, simple button controlled menus, embedded LCDs and beepers to make counts audible. Improved accuracy due to signal conditioning. Bluetooth interfaces for use with HydroTab Stream Gauging Computer available.

Gauging Weights (Columbus model):

Protects current meter against heavy debris damage, streamlined shape reduces resistance to flowing water.

HydroTab Stream Gauging Computer:

Assembly of HydroTab software and a tablet suitable for harsh and wet environments. Used for direct water velocity measurements, or collecting, calculating, displaying and emailing full river gauging data.

Wading Rods:

HyQuest Solutions’ range of top setting wading rods were developed to simplify the task of carrying out
gauging in small streams. We are happy to provide help in choosing the proper rod depending on your application and Equipment.

Winches (WS250, WS400, WS500):

Hand-operated single drum winches capable of handling Colombus gauging weights up to 70 kg using the four wheel bridge crane 4WBC. The winches are designed for ease of operation in the field: compact, portable, light-weight, and handled easily and safely by one person.
