Automatic Digital Water Level Stage Recorder

This is Micro controller based Automatic Water Level Recorder reflect state of the art in micro controller based instrumentation design. The Water Level sensor can be attached with this data logger for the collection of real time data automatically. The micro controller has its internal memory along with an additional 128K EEprom, a real time clock with an LCD (16 X 2) to display the instrument status. Digital Water  Level Recorder consist of a weatherproof enclosure which contains the data logger, level sensor and power supply, and comes complete with a solar panel and data shuttle. This system comes with three different sensor input combinations as per user requirement . Shaft Encoder type Level Sensor / Pressure type Level Sensor / Ultrasonic level Sensor.

Pygmy Water Current Meter (Cup or Propeller type)

Pygmy water Current Meter is used for Stream-flow measurements in shallow streams, flumes and small channels, where the velocity of water does not exceed 1m/sec. The principle of operation is based on the proportionality between the velocity of water and the resulting angular velocity of the meter rotor. By placing a current meter at a point in a stream by Wadding rod and counting the number of revolutions of the rotor during a measured interval of time, the velocity of water at that point is determined from the rating chart.

Digital Water Level Logger Pressure Transducer

The Levelogger Junior provides an inexpensive alternative for measuring groundwater and surface water levels. It combines a data logger, temperature sensor, pressure transducer, and 5-year battery, in a small, maintenance free, waterproof stainless steel housing. The Levelogger Junior features a non-volatile memory, with a capacity of 32,000 sets of temperature and water level data points. Readings are linear at a user-defined interval between 0.5 seconds to 99 hours. Accuracy is 0.1% FS, with a lifetime factory calibration.

Applications

Pump and slug tests
•Reservoir and storm water runoff management
Watershed and drainage basin monitoring
Stream gauging, lake and wetland monitoring
Tank level measurement
Monitoring water levels in wells and surface water

Water Level Indicator (Sounder)

The water level Indicator (Sounder) has been designed for water level measurements in streams, wells and up to 180 meters deep bore wells. It has a brass/steel probe connected with the shielded wire having markings at every meter. The dimension of the probe is such that it can easily be inserted in a gap of 2 centimeters. The wire is winded on a reel/spool, made of aluminum having a handle to fasten the wire. The probe is lowered into the stream or well or bore well, as the tip of the probe touches the surface of the water,. an in-built electronic circuit indicates contact with water by sounding a beep. Water acts as an electrolyte to complete the circuit. Depth is read from the attached cable and a measuring tape provided.

Suspended Solids/Silt Analyser

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 electronic with a solid –state, optical sensor. It is a multi-range indicator designed for the measurement of suspended solids in aqueous solutions. The microprocessor-based electronics of the indicator provide a high degree of flexibility and ease of use. Data logging and the ability to download the data directly to a computer are optional features. The indicator uses the model V5 sensor, which operates on the principal of single gap light absorption as the means of determining the concentrations typically found in aeration basins (1000 mg/L to 5000 mg/L) and RAS streams (7000 mg/L to 20,000 mg/L) of wastewater treatment  plants. There are independent calibration point for each. Furthermore, a 15L low range sensor (0-1000 mg/L) is also available. The model V5 sensor was designed to measure very low solids concentrations typically found in secondary clarifier and plant effluents. The sensor utilizes and infrared emitter to minimize color effects and compensates for emitter variations due to temperature by measuring source brightness.

Suspended Sediment Sampler (USDH-48 or 59)

This depth integrating type suspended sediment sampler is used to collect the sediment samples. The sampler consists of a streamlined metal body provided with tail fins to permit alignment in the flow direction. The container for sediment-water mixture is usually a bottle housed in the metal body capping after the sample has been obtained seals the bottle. This sampler is used in shallow streams when the product of the depth (in feet) and velocity (in feet/sec) does not exceed approx. 10. This sampler is used with wadding rod suspension
