Open Stream Current Velocity Meters

The sensor has a propeller-driven, photo-fiber-optic device with a 2" propeller sweep diameter. Measurements can be read in feet or meters on your choice of two digital readout indicator models, both with better than 1% accuracy.

Model 2100 Indicator

The Model 2100 accommodates all types of open flow streams – three selectable pre-set display update times (90 second maximum). Powered by a 9 V battery, its self-calibration feature allows you to check accuracy of the instrument while in the field. Precision quartz crystal controlled electronics provides accurate, precise data in all flow conditions.

Model 3000 Indicator

Designed for the measurement of open channel velocities and the on-site computation of stream discharges, the Model 3000 replaces the dial-style control of the 2100 with a keypad. The Model 3000 is a datalogging version of the 2100, and records depths, widths, velocities, flow angles along with time and date (stations). It is also capable of measuring stream discharges. The velocity sampling interval is selectable from 1 to 999 seconds. The memory is capable of holding 1000 stations in up to 100 cross sections for later upload to a PC. Simple, accurate calibration is possible in the field, and calibration ratings for 10 different sensor options are stored. Powered by four "AA" size batteries, the Model 3000 is designed to function with Price type "AA" and Pygmy meters with or without optic sensors.

Sensor

The sensor uses a 2" propeller which rotates a fiber-optic bundle to create a signal from a photodiode to a photosensitive transistor. This signal is produced at a rate of four pulses per revolution and is transferred via flexible electrical cable to the indicator where it is processed to display velocity. The propeller is swivel mounted at the foot of the wand (handle). The wand carries the cable to its upper end from which the cable extends to the indicator. The sensor wands are aluminum alloy with stainless steel fasteners. The propeller is a glass impregnated nylon and all other plastic sensor parts are acetal-resin.
All models consist of the meter (2100 or 3000) and the Wand (-STDX, - 14, -1514 etc.). All Meter/Wand combinations listed below are “fieldready”, i.e., the following required equipment is included: Two sets of batteries ("AA" or 9 V), two complete propeller rotor assemblies, spare propeller, hands free harness and/or neck strap, sensor and cable assembly, wand, operating instructions (on paper and floppy disk), Model 3000 also includes DB9 style serial connector /cable and software for file transfers to a PC.
