Overview
PRODUCT DISCONTINUED - REPLACED BY THE SIGNATURE FLOW METER
The 4210 Ultrasonic Flow Meter from ISCO is designed to provide open channel flow measurement in a flume or over a weir, with automatic compensation for changes in atmospheric pressure to ensure accuracy. The non-contact ultrasonic sensor transmits a pulse of sound that is reflected by the surface of the liquid and the time elapsed between sending and receiving determines the level of the liquid in the channel.
As the ultrasonic level sensor does not contact the flow stream, long-term stability is achieved without the need for scheduled maintenance. The 4210 is also not affected by harsh chemicals, grease, silt or suspended solids in the flow.
Stored data can be retrieved with an on-site laptop PC, and Isco 581 Rapid Transfer Device, or remotely using an optional modem. Isco's Flowlink software is required for advanced graphing, reports and analysis of data.
Standard Features
- 160 character backlit LCD
- Built-in flow conversions for most applications including data points, Manning formula, or equations if needed.
- Accurate on-site printouts using built-in dot matrix printer.
- Large internal memory can store 2 months of flow, parameter, rainfall and sample data taken at 15 minute intervals.
- Possible false echo problems caused by obstructions such as manhole rungs are eliminated using Variable Blanking Distance.
- Automatic Gain Adjustment - in response to echo strength. Maximises performance in the presence of foam, stem or turbulence
- Provides interface for sampler activation - connection to multi-parameter water quality sonde and alarm outputs.
