CURRENT METER, CUP-TYPE

Specifications

Sensor model                      6 cup wheel

contact                               every one revolution

range                                 0.05 to 3.5 m/s (starting up to maximum operational velocity)

accuracy                           for velocities up to 0.3 m/s           1 % Full Scale

                                          for velocities >0.3 m/s           0.5 % FS

  contact chamber                                magnetic or optic fibre

2. Suspension Wading

wading rodtotal length 3 m, graduation in cm
electrical cablerunning from current meter to counter, 10 m

From a cable

suspension cable electrical cable integrated in suspension cable electrical cable from winch to counter, 7 m

cable torque                                     torque free suspension cable

The suspension cable should not exert any torque that may adversely affect the alignment of the flow sensor into the direction of flow. In particular in case a heavy suspension weight is used,

there is a risk of cable induced torque.

suspension-rod                               for cable suspended measurements with light weight sinkers

tail fin length                                    >0.25 m beyond the attach point of the suspension

The tail fin shall be capable of aligning the current meter in the direction of flow and keep it stable in that position throughout the full velocity range.

3. Fish weight

model                                                USGS Columbus or similar

material                                             lead

finish                                                 smooth, painted surface

mass                                                  25 Kg- 1 no and 50 kg-1 no per set.

If the instrument is used from a cable way then an integrated bottom detector is required

suspension   bar fitting current meter and cable terminal

Accessories
  • standard instrument tools
  • spare bearings
  • carrying case for current meter with counter
  • carrying case for fish weight(s)

Tape Specifications of water level Sounder:

1. MATERIAL: PVC Coated Steel Measuring Tape – Two Wire
2. STRENGTH is assured through an inner core of extreme tough Glass Fiber and an overlay of protective Poly Vinyl Chloride. The tape breaking point is more than 2,000N.
3. LEGIBILITY is excellent as all marking are printed on inner steel tape with ultraviolet-fixation permeating ink. Thereby, the markings will never come off for years of use.
4. Probe Diameter: >15mm,
