Hydrological Instruments

Description This apparatus demonstrates some of the major physical processes found in hydrology. The unit comprises a rectangular open Sand tank, made of stainless steel. At inlet side, another tank of stainless steel is fitted with stilling section. A junction of nozzles is fitted on the top of the sand tank. This junction is provided with the variable height adjusting arrangement. Every nozzle has a valve which facilitates to select combination of nozzles and geometry of rain fall. The Water is fed to these nozzles with the help of a centrifugal pump connected to a sump tank. A valve arrangement is provided to change the water flow either through nozzles or direct to the tank. A Rota meter with integral adjusting valve is used to control and measure the various flows into the sand tank. Sand is filled in the tank to conduct the experiment (sand is not in the scope of supply). At outlet side of the sand tank, a stainless steel tank with weir arrangement is also supplied to measure the outlet flow from the sand tank. The sand tank also has pressure tapings which are connected to manometer to observe the water level in the sand tank during the experiments. A screw jack arrangement with hand wheel is fitted to tilt the sand tank and angle of the tilting can be measured with the help of a scale provided. Sand tank also incorporate two wells. Present set-up is self-contained water re-circulating unit, provided with a sump tank, centrifugal pump etc. Water is pumped by means of centrifugal pump and passing through the Nozzles and Sand Tank, it returns back to the sump which make the system re-circulating type. Flow control valve and by-pass valve are fitted in water line to conduct the experiment on different flow rates.

We are proud to offer high tech Siltometer as part of our product range. The technologically advanced Siltometer offered by us is widely used for measuring settling rate of particles in column of liquid (usually water). Our Siltometer uses incremental method, to measure this settling rate and determines the rate of chain of concentration of the suspension at a known vertical distance below the upper surface of the suspension. The optimum performance, easy operations and accurate measurement, makes our Siltometer the best available digital meter available in the market. Variants : Optical Lever Siltometer : Method used : Incremental method Use : determines Indirectly the rate of chain of concentration of the suspension at a known vertical distance below the upper surface of the suspension Puri`s Siltometer : Method Used : Cumulative method Use : To measure the rate of accumulation of the material by measuring the deposited sediment at the bottom of the tube

This setup can be used to study seepage and groundwater flows after precipitation. Furthermore, sediment transport in courses of rivers is also presented in the context of flow obstacles. Variable precipitation density and areas and different groundwater supply and drain possibilities allow a wide variety of experiments. The setup contains a closed water circuit with a storage tank and pump. The core element is a sand-filled, stainless steel experiment tank with inclination adjustment. To study precipitation, a precipitation device is available, which is equipped with a timer to define the times of precipitation. The precipitation device consists of two groups of four nozzles. Water can flow in (groundwater) or out (drainage) via two chambers on the side. The experiment tank is separated from the chambers by fine mesh screens. To study the lowering of groundwater, two wells with open seam tubes are available. By means of a small weir in the supply and drain, a course of a river can be generated. Different water levels can be generated. Water supply and water drain can be opened and closed, thus allowing a wide variety of experimental conditions. In addition, three different models make it possible to study the flow around obstacles and the resulting sediment transport in the river bed. At the bottom of the experiment tank there are measuring connections to detect groundwater levels, which are displayed on 19 tube manometers. Two flow meters with different measuring ranges indicate the supply to the experiment tank. A measuring tank at the drain contains a measuring weir for determining the water level and a force sensor for determining the amount of sediment.

This Measuring Crane is manufactured for lowering heavy instruments i.e. water current meter along with heavy fish weight (approximately 50kg) for measuring the water s velocity. This Crane is also used to take the sediment silt by using silt sampler. Easy in operation and movement. It can be folded to make easy for transportation and fix it very easily at another side. Crane boom is move around on vertical axis and boom is kept parallel to surface of road, bridge, or boat when we operated on curbs or side walls.

The horizontal chart drum of the type F automatic water stage recorder which actuated by flot action through the float pulley and is rotated proportional to the changes in the water levels. The Pen moves across the chart from left to right at a multi- speed by means of quartzes clockwork operated by D.C, cell. With 100 graph sheets and ink.

Description: Basic hydrology services involve the study and analysis of water resources, including precipitation, runoff, and water quality. These services help assess and manage water resources for various applications, such as flood control, irrigation, and drinking water supply. Hydrological analysis supports informed decision-making for water resource management, infrastructure design, and environmental sustainability. It provides valuable insights for stakeholders and policymakers.
