Description
Features of Current Meter
- The design for reliable and accurate field data under the prevailing Indian environmental conditions and under cyclonic weather condition.
- The system shall be easy to operate and maintain.
- The current meter can be fitted with a stabilizer tail fin which is attached to a hanger bar and Colombus gauging weight in sizes of 7, 15, 23, 34, 45, 68, 90 or 135 Kg. This assembly is suspended from a gauging winch with armoured signal cable. A rating table is used to convert number of pulses to velocity.
- The current meter is of Type “AA” current meter. It allows the measurement of water flow in streams, open canals, pressure pipes & lakes to a fine degree of accuracy and repeatability with its advanced contact switching system and interchangeable impact resistant bucket system that provides trouble free operation.
- The current meter is made to be used in the most extreme environments and ensures reliable field service for many years.
- The current meter is supplied in a kit which is affordable and user friendly, allowing the operator to measure water flow using a simple traditional method.
Current Meter Working Principle: Water Flow is measured through pulse signal produced per revolution. This signal is generated by an encapsulated reed switch which resides inside the current meter body.
Accessories:
The wading rod can be use with current meter as well as ADCP as positioning system. The water depth is displayed along with the % depth as the rod is moved up and down as well as the ‘Point’ velocity through use current meter / ADCP.
Features:
- A feature of the device is its ability to “clean” the signal and interface directly to a compatible PDA, Pocket PC, or other computing device and provide serial data that can be used by the external device to compute discharge.
- Suitable for current meters with either magnetic reed switch or cat’s whisker contact.
- In-built current meter signal processing feature to verify current meter signal and detect any ‘shorts’ in connections.
- The water velocity is directly computed and displayed on an LCD.
- LCD (with backlighting) to display sounding and depth of observation
- Easy to read ruler on rod Push button selection for either IMPERIAL or METRIC measurement
- Keypad mount (Optional) to suit for ADCP
- Electronics housed in IP66 water-proof enclosure
- Displays current meter counts (selection of timing intervals from 10 to 90 seconds)
- Support NORMAL (> 0.08m/sec) and SLOW (< 0.08m/sec) speed operation
- Spin test feature & Dwell test feature
- Integrated Bluetooth interface (Spec V1.1)
- Powered by 3 x type ‘AA” alkaline batteries (approx 50 hours continuous use before discharging)
- Durable and light-weight aluminium and stainless steel construction
- Canvas carry bag included
