Open Channel Flow in Flume or Weir

Non-Contacting Open Channel in Flume or Weir

Greyline’s Open Channel flow meter continuously measures, displays, transmits and controls liquid level in storage tanks and pumping stations.

It also measures the open channel flow through any flume or weir. Calibration is simple with the built-in 5 button key pad and the isolated 4-20mA output transmits level or flow.

There are 2 built-in programmable control relays. The optional built-in data logger stores 26 million points data logger and flow reporting system and the data is easily downloaded to a memory stick via the built in USB port.

Accuracy of ±0.25% of Range or 2 mm (0.8 in) whichever is greater and
repeatability & linearity of ±0.1%

The OCF 6.1 flow meter that doubles as a tank level meter, making it a perfect solution for both non-contacting flow measurement and level measurement. The ultrasonic sensor supplied with the OCF 6.1 mounts just 203.2 mm above the flowing water giving +/- 0.25% accuracy.

Use the OCF 6.1 Open Channel in flow mode for non-invasive flow, irrigation flow monitoring, industrial flow monitoring, and influent and effluent flow.

The OCF 6.1 for open channel flume or weir has the following features

Non-Contacting Ultrasonic Sensor
Large, Backlit LCD Display
12-Digit Totalizer
Isolated 4-20mA (1000 ohm)
2 Programmable Control Relays
Automatic Sensitivity Adjustment
Built-in 5-Key Calibrator
Optional 26 million point data logger with USB output to flash memory

Water meters are needed across all industries for precise flow measurement and control, with advanced meters available in ultrasonic, magnetic and differential pressure types for different applications and environments.
The selection of the correct flow meter is critical and should be based on specific considerations such as medium type, flow range, environmental conditions, and regulatory compliance, with accurate sizing to balance sensitivity and pressure drop concerns.
Keeping water meters performing optimally requires proper installation and routine maintenance.
Flow meters have transformed our approach to measuring and controlling flows, making them a trustworthy solution for a wide range of systems. Regardless of the application, there is a flow meter that fits the bill.
