Chart type Water Level Recorder serves for continuous registration of water levels in flowing and stagnant waters. The registration will be effected on a 16 m long diagram roll. Mainly this instrument will be used for discharge Measurement, irrigation & ground water studies

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

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 basic version of the measuring equipment consists of is a sensor with an analogue output (4...20mA). According to a modular concept the SEBAPULS can be equipped with an additional measuring value storage (i.e. SEBA Data logger MDS-Dipper) and a remote transmission (via GSM network, fixed network etc.).

Logger, GSM/GPRS modem, antenna and LC-display are located in the  folding top. A sophisticated energy management (time-slot procedure) cares for long battery life times and thus for low maintenance efforts. SMS alarms can be sent to 4 different mobile phone numbers, as well as to a facsimile instrument.

Equipped for measuring up to 16 different water quality parameters, the instruments provide the highest level of information about the conditions of the monitoring site. Specifically designed for field applications, the MPS sensors can be used under harsh conditions, e.g. in tropical, arid or arctic zones. They are robust enough for all kinds of fieldwork and measure with maximum accuracy. As it is possible to use optical sensors, a long term stability with low maintenance effort is guaranteed

The Ductus COI is an universal transit time ultrasonic flow meter. With the advanced large scale integrated circuit technology, it is well suited to most industrial environments for continuous flow measurement of homogeneous liquid. Although the system was designed principally for clean liquid applications, the instrument is tolerant of liquids with small amounts of gas/air bubbles or suspended solids found in most industrial environments. The flow meter use state-of-the-art digital electronics and very powerful ultrasonic transducers to give high accuracy for pipe sizes between 25 mm and 5000 mm. The stationary unit consists of a wall mount electronic housed in a Nema 4x enclosure and two clamp-on sensors that are permanently clamped to the outside of the pipe. The electronic offers an easy-to read two-line LC-display with a 16-button keypad for setting up the parameter. The unit is powered from a mains or DC voltage supply. A 4-20 mA current loop output, as well as pulse and frequency outputs, enable the unit to be used for continuous monitoring of flow where it is required to spot-check the operation of pumps or other process equipment, A portable version is available

The Transit Time Flow meter of TTFM100B series 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.

This Micro-controller based Direct 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 current meter sensor are provided on the top. One power connector for charging adopter is also provided.

The suspended solids Indicator is a state of the art, easy to use meter that provides many benefits to the plant operations staff. It is a unique system that combines advanced electronics with a solid-state, optical sensor. It is a multi-range indicator designed for the measurement of suspended solids in aqueous solutions.

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.

Applications:

Hydrological investigation.
Monitoring pore-water pressure to determine the stability of slopes, embankments, and landfill dikes. 
Monitoring ground improvement techniques such as vertical drains, sand drains, and dynamic compaction. 
Monitoring dewatering schemes for excavations and underground openings. 
Monitoring seepage and ground water movement in embankments, landfill dikes, and dams. 
Monitoring water draw down during pumping tests

This is the most common type of suspended sediment Sampler it consists of a metallic one litre capacity bottle held vertically in the metallic frame at one of a adequate length of pipe with lever attached to the lower end and a flexible wire running with the help of one spring and lever for opening and closing the mouth of bottle fitted with rubber cock during sampling. The sampler has advantages, of low cost, simplicity in design and operation.

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.
