Virtual” make Digital Water Level Recorder (Radar Type) is a fully computerized, digital and self contained power source system, fitted with Data Logger and battery charging solar panel with rechargeable, maintenance free batteries complete with sealed waterproof enclosure for Data Logger, Solar charger and battery. It should be complete with facility to transport Data from Data Logger to a P.C. through a pocket able data shuttle. 16-x1 alphanumeric display and 4x2 membrane keypad is provided at front panel of data logger for programming data logger and monitoring sensor reading at site without the help of computer. This system used SEBA make Radar type Level Sensor. In the so called pulse principle a short microwave impulse is emitted. Then the sensor rests for a short time. During this time the radar receives the echoic signals reflected by the water, then the signals are transmitted to the integrated evaluation system. The runtime of the impulses matches the distance to the actual water level.

The SEBA pneumatic gauge type "PS-Light" is a robust, reliable and economic measuring system for monitoring water level in surface waters. The measuring principle is based on a version of the bubbler system, well-known and proven by the other SEBA instruments of the PS-series. At adjustable intervals an integrated, highly efficient mini compressor bubbles air through the pressure tube into the water. The pressure generated in the tube corresponds exactly to the hydrostatic pressure above the mouthpiece. This tube pressure is measured by a high-precision pressure sensor inside the PS-Light

Response is seen on LED plus an audible tone is heard. Features include: Standard cable lengths: 90 mtr. brass electrode is field replaceable. Reel-type spool for lowering cable and electrode assembly. Reel is mounted on a tubular stand. Self-contained 9V battery power supply – no danger of shock from an outside power supply. Battery test. Standard brass electrode. Reel handles are shaped to fit your hands. Accurate to ±1% of reading. Each Water Level Indicator is supplied with a battery.

River Staff Gauges are useful for the manual measurement of River / Canal / Lake water level. Different sizes and types for River Staff Gauges are available with us

The Transit Time Flow meter of measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream go into a full pipe. This flow meter is mostly used to measure the flow rate of homogeneous fluids, with a very little percentage of suspended solids and possibly without gas bubbles. Its peculiar installation makes these devices suitable for measuring aggressive fluids (acids, basic and dissolvent’s) or very soiling fluids (oil and fuels). The measuring system is composed of one or more couples of ultrasonic transducers acoustically coupled to the external pipe’s wall (it is also possible to use transducers in direct contact with fluid to be measured) and a portable unit elaborating the sent and received signals from the transducers. The HOST unit has a DSP microprocessor; it gives signals to interfacing with the process or the control systems.

You can use cup type current meter  using a cable with sinking weight or wading rod and will accurately measure stream flow velocities from 0.3 to 3.5 meters per second with cups. (Also available in measuring range up to 6 meter per second) The cup type current meter manufactured as per IS 3910 – 1966. You can connect this current meter to an automatic counter / Water Velocity indicator (Sold Separately).  The calibration chart provided with the meter gives the velocity in m/sec .

This current meter is used with wading rod and will accurately measure shallow stream flow velocities from 0.01 to 3.5 meters per second. Manufactured as per IS 3910 – 1966. You can connect this current meter to an automatic counter / Water Velocity indicator (Sold Separately).  The calibration chart provided with the meter gives the velocity in m/sec

This Micro-controller based Water Velocity Indicator has been designed to measure the Velocity of water in a flowing stream. It uses the latest Microchip’s Micro-controller and can be used with any calibrated Water Current Meter. The velocity of water is calculated as per the calibration equation provided with the Sensor and displayed on the 16x2 LCD display. The Velocity Indicator consists of 4x1 tactile membrane keypad mounted on the front panel. You can save up to 56 readings. Two terminals to connect the different types of current meters sensor are provided on the top. One power connector for charging adopter is also provided.

Water Temperature Profiler:

The durable Water Temp Pro has 12-bit resolution and a precision sensor for ±0.2°C accuracy over a wide temperature range. A temperature-compensated real time clock provides better than ± 1 minute per month time accuracy. Designed with a durable streamlined case for extended deployment in water up to 50°C, the Water Temperature  Profiler is equipped with an infrared (IR) interface for data offload in the field, even when the logger is wet.

The Porous tube Piezometers are used to monitor piezometric water levels. Observation wells are used to monitor ground water levels. Water level readings are typically obtained with a water level indicator. This is a device for measuring pore water pressures primarily in a foundation though it can also be used to measure pore pressure in an embankment. It is more sensitive to foundation pressures or ground water fluctuations and is more resistant to plugging due to silting than the conventional observation well which it replaces. The porous tube Piezometers may not indicate the correct pressures where sufficient flow of water into the standpipe of the Piezometers is not available as in partially saturated soils. This is a porous tube of annular cross-section, 37 mm outer dia x 6 mm wall thickness and available in two sizes 12 Inch & 24 Inch long. The porosity of the porous tube is chosen according to site conditions. Unless specifically requested, the porous tube filter has a grain size of 60 micron.

This equipment is useful for lowering and lifting heavy instruments like-current meter with fish weight for measuring stream velocity and obtaining sediment studies from the road bridge sites or from boat amid the rivers. This is made from sturdy angle iron sections and very portable for moving from one place to another. The rear assembly is adjustable in a vertical direction so that the platform surface will remain parallel with the road surface when operated on curbs or side walks. The handle is collapsible, folding up underneath the truck for ease of transportation and storage.

Cableway System:

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