USGS Top Setting Wading Rod Breakdown Top Setting Wading Rod USGS AquaRod 2100 USGS Standard Wading Rod Set Universal Wading Rod

The standard USGS Top Setting Wading Rod is intended for use with the Type AA and pygmy current meters. It is designed for measuring shallow streams, with the standard English rod marked in feet and tenths and comes in 4, 6 and 8-foot long models. The standard metric rod marked in centimeter increments with a length of 1.2 meters. These wading rods also are available in lengths (up to 10 feet or 3 meters long) as desired by the customer. The anodized aluminum handle has an integral scale to indicate the correct setting of the current meter at the 0.2, 0.6 and 0.8- depth settings, which corresponds to the conventional two- position method. This unit permits convenient setting of the current meter at the proper depth. It allows the hydrologist to quickly set the meter at the correct depth without bringing the meter out of the water. The depth of the water is read on the graduated hex main rod. When the round setting rod is adjusted to the depth of the water, the current meter is automatically positioned for the 0.6-depth method (0.4-depth position up from the streambed). Setting the unit to half the water depth will place the meter at the 0.2-depth up from the streambed. Conversely, setting the unit to twice the water depth will place the meter at the 0.8-depth position up from the streambed. The latter two positions correspond to the conventional two-position method. The electrical lead to the current meter is supplied, and a standard plug is fitted into the handle to accept the leads from a headphone, counter or AquaCalc 5000. The commonly used two prong connector can also be supplied as required. All parts are made of stainless steel, anodized aluminum and brass.

                        

Vernier Setting	Actual Current Meter Position
Exact Water Depth	0.4 up from the streambed
Twice Water Depth	0.2 up from the streambed
1/2 Water Depth	0.8 up from the streambed

USGS AquaRod 2100

The USGS AquaRod 2100 is an exclusively patented, electrically isolated 4 ft. top set wading rod for high conductivity streams. The AquaRod is a top set wading rod in which the signal from the current meter is totally insulated for maximum signal integrity for the AquaCalc 5000 flow computer.

The Standard Wading Rod Set consists of four sections of 0.5 inch diameter graduated rod, a rod base, a double end meter hanger, an upper binding post, a 10-foot connecting cable with double or single connector, wire retaining clips, and a sewn canvas carrying case. The wading rod is graduated in tenths of a foot in its entire length, reading 8 feet from the plane of the bucket wheel. Rod sections are assembled at the screw-in flush joints. The metric rod is 2.0 meters long and consist of four 0.5m sections. The USGS Standard Wading Rod can be used with either the Type AA or Pygmy current meters. Extra rod sections may be ordered separately.
