The cable way installation is provided for determination of current velocities in water courses, canal and rivers. Depending on the kind of water and maximum possible current velocities suspended current meter equipment with snikers of 25,50and 100kg and more can be used .By means of double drum winch, the meter body can be moved horizontally and vertically. The corresponding position of meter body can be determined with the help of the two counters. So a determination of current velocities from river bank is possible. Due to the solid execution of stationary cable way installation is a safe operation is possible in extreme conditions ( Flood , extensive span etc).

Inserting a screened sampler to the desired depth in the formation and then exposing the screen collects groundwater. In order to yield groundwater, the screen must be left in place for an undetermined amount of time to allow for groundwater recharge. Groundwater is collected after bailing or purging using 1/4 inch tubing and a check valve.

Groundwater sampling is performed using a Geoprobe Screen Point 15 Groundwater Sampler. The sampler is used to "grab" representative groundwater samples at specific depths.

The Propeller Type Water Current Meter is used to measure Velocity of water flow directly in m/s. The stainless-steel spindle carrying the cup wheel freely rotates in the bearing assembly. The magnet and reed switch assembly produces one pulse per rotation. The rotation of the Water Current Meter is sensed by sensor & gives pulsed output signal. As per IS: 3910-1966, the Water Current Meter employs a bucket wheel assembly that is mounted upon a shaft and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current bucket wheel assembly is made of plated brass. It employs six hollow conical cups that are hand formed from sheet metal and individually soldered to a brass, star-shaped frame. The finished unit is then plated. The frame is shaped so that a strut connects the apex of each cup to the outer diameter of the following cup around the frame. The Propeller Type Water Current Meter can be suspended by means of a Fish weight while wading a stream, or by a cable and wading rod from an overhead structure. A tailpiece assembly assures proper alignment of the meter to water flow when suspended by a cable. Velocity is determined by counting the number of revolutions of the bucket wheel over a given period of time. Revolutions can be monitored by several means. The Digital Water Velocity Indicator / Logger (sold extra) by configuring the indicator with calibration equation (provided with each meter), it will result the direct current velocity of the stream in Meter per second. The meter is made from brass and stainless steel and all exposed surfaces are chrome plated for corrosion- free service. Each Current Meter is provided with a standard rating table to convert bucket revolutions to stream velocity in Metric units (meters per second), spare parts, instrument oil, cleaning cloth, screwdriver and a rugged carrying case.

The water current meter used for determining velocities of flowing water in open channel and streams has been manufactured to meet the requirement of IS:3910.

The water current meter consist of a cup type bucked wheel assembly having six cups mounted on a vertical shaft. This shaft is held vertical in a yoke frame on two pivot points. This yoke frame while holding the moving the moving assembly protect its cups from damage from the floating bodies in flowing water also. The vertical shaft rest on a pivot point at the lower end which is adjustable. the upper end is held in position at a pivot point inside the magnetic contact chamber, which is made water right by a cap. The magnetic contact chamber is equipped with two contact switches the terminal of which are located outside on the body of the contact chamber. Only one switch is used at a time, the other is a spare and stand by and can be used immediately if one goes out of order. The other end of the contact terminals (earth) is the yoke frame itself and so a common earth terminal has been provided on the yoke frame. The bucked wheel rotates in between two pivots in the yoke frame. Each one revolution of the buckets wheel makes a contacts of the magnatic switch in the magnetic chamber which can be recorder on a counter. The yoke frame consist of a tail fin with a balancing weight, which moves in a slot and be adjusted at any place within the slot. The balancing weight is so adjusted so as to keep the current meter horizontal when suspended in water. The tail fin keeps the yoke frame with the bucket wheel to the upstream direction as the tail fin goes to downstream direction with the flow of water. The meter is suspended in water with the help of a suspension flat in deep water and by a suspension rod (wadding rod) in shallow water.

Sunshine recorders automatically registering time and duration of insulation are used at meteorological and climatologically research centers, observatories, spas and health resorts, in agriculture, horticulture, viticulture and vegetable gardening. The instruments are set up on flat roofs or on clear ground in such manner as to be well exposed to solar radiation, during the whole day. The type of instrument to be chosen depends on the latitude of the place installation. This recorder consists essentially of a glass sphere mounted concentrically in a section of a spherical metal bowl, the diameter of which is such that the sun stays are focused sharply on a card held in the grooves, in the bowl. Three overlapping pairs of grooves are provided in the bowl to taken up cards suitable for the different seasons of the year.
