WATERMARK Sounding Reel & Sounding Weight - Alat Survey

WATERMARK Sounding Reel & Sounding Weight

The bridge board was designed for use in making discharge measurements and obtaining water quality samples from off of bridges. It is a free-standing support, accommodating A-Pack, A- 55 or B-56 sounding reels. It comes with an adjustable foot rest which makes it easily adaptable to bridge railings of different heights and walkways of various widths. In use, the Bridge Board is set to the approximate height of the bridge rail at the measurement site. With the sounding reel secured to the mounting plate, the boom is positioned so the sheave extends out past the bridge rail. The suspension cable is now stretched out over the sheave at the end of the 4 foot long boom. The current meter or sampler is then suspended from the cable and is in position to be lowered into the water below. The maximum sounding weight to be used with the bridge board is 50 pounds ( 23 kg) .
The A-Pack Reel is used to position stream gaging and sample collection equipment. The reel is small and compact and was designed for use at remote sites where it is necessary for the hydrologist to backpack or hand carry the stream gaging equipment for some distance. It is for use with weights up to 50 pounds ( 23 kg) . The USGS bridge board mount plate and the cable car reel mount plate are drilled to accommodate this reel. The reel is equipped with a removable handle, and is equipped with a counter to measure water depth in feet. The drum has 45 feet ( 13.7m) of 0.10 in. Ellsworth cable. The A-Pack reel comes in a steel carrying case as shown with the reel. See the Technical Data page for more information on sounding reel selection.
The A-55 Sounding Reel is used to position stream gaging and sample collection equipment. The reel is used with weights up to 100 pounds ( 45 kg) and holds 75 feet ( 22.9 m) of 0.10-inch ( 0.25cm) cable. The reel can be mounted on Type A and Type E cranes, the bridge board, the sit-down or stand-up cable car, and the boat boom assembly. The A-55 reel is equipped with a USGS-type computing depth indicator and can be furnished to read in either English or metric ( A-55M) units.

SWOFFER 2100 Stream Current Velocity Meters - Alat Survey

SWOFFER 2100 Stream Current Velocity Meters

A portable, reliable means of measuring open stream velocities in the range of 0.1 to 25 feet per second or 0.03 to 7.5 meters per second ( selectable) . Measurements can be read in feet or meters on your choice of two digital readout indicator models, both with better than 1% accuracy. Each meter includes a meter indicator, shoulder strap and snap ring, and PVC shipping/ storage tube for the sensor. 2100 Series includes a 9V battery, and the 3000 series includes four AA batteries.
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 transferred via cable to the indicator where velocity is displayed. Resolution of the display is to hundredths. The propeller is swivel mounted for easy storage. A quick-disconnect, waterproof cable connection is located at the indicator. The electronics of the sensors are permanently encapsulated in epoxy resin and housed in chemically inert acetal-resin fittings. All sensor parts are replaceable and are available separately. Sensor wands are aluminum alloy with stainless steel fasteners. Propeller is glass impregnated nylon and all other plastic sensor parts are acetal-resin ( Delrin or Celcon) .
Model 2100 Indicator

Accommodates all types of open stream flows. Three selectable, pre-set display update times allow up to 90 seconds of averaging. In extremely turbulent flows, otherwise unreadable data is electronically averaged and can be used without interpolation. Features a dial style control and self-calibration to check accuracy of instrument while in the field. A compartment in the back of the indicator houses the battery and has space for one spare. Liquid crystal display features one line with 0.7" H digits.

GLOBAL WATER PF 111 Flow Frobe Velocity Meter - Alat Survey

GLOBAL WATER PF 111 Flow Frobe Velocity Meter
