Flow Meter, Current Velocity Meter, and Sensor Wands



Model 3000 Flow Meter and Model 2100 Current Velocity Meter

 流  速  記
Model 3000 Flowmeter      
Records depths, widths, velocities, flow angles, time/date ("stations")
Memory holds 1000 "stations" in up to 100 cross sections for later upload to a PC
Calculates discharge
Velocity sampling interval is selectable from 1 to 999 seconds
Calibration ratings for 10 different sensor options are stored
Powered by four AA size batteries
Designed to function with Price type AA and Pygmy meters with or without optic sensors
Can be easily field-calibrated to operate with any contact closure type sensor



Model 2100 Current Velocity Meter    
Read stream velocity directly from 0.1 to 25 feet (.03 to 7.5 meters) per second
Data displayed in either feet or meters per second
Three selectable pre-set display update times. 90 second maximum
Powered by a single standard 9V battery.
Uses the efficient, propeller-driven Photo-Fiber-Optic sensor
Precision quartz crystal controlled electronics provides accurate, precise data in all flow conditions


Pelican© cases are an ideal way to transport and store your meter safely.

Wands
Wands are classified in three different categories; Combination, Top Set Wading, and Telescoping. All of these wands are designed for, and supplied with, the line of current meters (see above).



Combination 
Combination rods are designed to measure flows in faster, deeper water. These wands can be used from low bridges, boats, manholes, or while wading. The segmented 1" diameter thick-walled aluminum tube construction provides the rigidity to withstand higher flows. These rods are supplied with a Top Cap with direction pointer, a Slider (to hold the sensor) and a 2" diameter Foot.

-1514
12' total length, 4 sections of 3' each
Hash marks are in feet and tenths of feet
Wand breaks down via stainless steel threaded fittings
Extra sections, with or without hash marks, are available
Sensor cable supplied is 25' in length.
-1518
4 meters total length, 4 sections of 1 meter each
Hash marks are in meters with 5cm increments
Wand breaks down via stainless steel threaded fittings
Extra 1 meter sections, with or without hash marks are available
Sensor cable supplied is 25' in length.


Top Set Wading Rods
6/10 Depth Method rods are designed to be used while wading in streams, waterways and channels. Stream depth is noted using the larger graduated rod, then the corresponding marks on the smaller rod are used to slide the sensor to 6/10 of the depth from the stream surface, a standard average velocity depth in shallow waters. Top-set wading rods shown differ only in their depth measurement capabilities.

-C140

Measures water depth to 140cm
Marks in 5 centimeter increments

-C80

Measures water depth to 80cm
Marks in 5 centimeter increments

Telescoping 
Telescoping wands are designed for reaching shallow and partially obstructed channels. Both length wands are supplied with the sensor on an 8 inch boom for easy reach into side sewers (a shorter, 2 inch boom is also available). Simple but rugged all-stainless steel hose clamps provide positive section locking with minimum field maintenance. A L diameter stainless steel depth probe with 1" dia. aluminum foot is supplied and can be attached to the bottom of the extended lower section. The depth probe is used for repeating measurements from a specific distance off the channel bottom. The probe has no hash marks. Enough connection cable to reach 5 ft. beyond maximum wand extension is provided.

-LX

Designed for slower, shallow flows requiring a long reach such as in sewers
Min. length: 4.5 ft. / Max length: 19.5 ft. @ full extension
Each telescoping section (5) is 4 ft. in length
2 inch to 3 ft. adjustable depth probe (probe has no hash marks)

-STDX

A compact version of the -LX above.
Min. length: 2.5 ft. / Max length: 9.5 ft. @ full extension
