• Built-in ISO 1438 flow formulas
• Flow-proportional control of sampler
• Adapts to any kind of weir or flume
• Built-in stormflow function

• Supplied with either ultrasonic or hydrostatic sensor
• Maximum accuracy with measuring ranges down to 0-10 cm
• Flow Converter 713 is calibrated from the front panel
• Easy to operate with setup information in English or other user-specified language
• Security access code can be programmed
• Built-in totalizer with counter
• Indication of average flow (m3/hour) actual, the last hour, today, the last 24 hours
• Indication of accumulated flow (m3) actual, the last hour, today, the last day
• If 713 is set as an emergency stormflow meter, the number of stormflows, stormflow time and volume and start and stop time for the last stormflow are counted
• Alarm can be set for high and low flow, and excess of 1- and 24-hour volumes

The sensor of the Flow Converter provides a signal proportional to the level. 
The amplifier linearizes the signal from the sensor so it is proportional with the flow rate.

• Preprogrammed formulas for different dimensions of the most common flumes and weirs such as Parshall, Venturi and Palmer Bouwlus flumes and retangular or V-notch weirs based on ISO 1438.
• When using non-standard flumes or weirs the existing calculation formula can be programmed.
• For flumes where no calculation formula exists, a number of known Level-flow values can be entered, on the basis of these a point-linearization is made.
