River velosity registraytor RVR-11 is a device designed to determine the average water flow rate.
Features:
- replaceable bladed propellers with a diameter of 70 and 120 mm;
- the measurement range of the device with a bladed screw of a turntable with a diameter of 120 mm is from 0.03 to 5.0;
- the measurement range of the device with a bladed propeller of a turntable with a diameter of 70 mm is from 0.06 to 5.0;
- the number of revolutions of the bladed propeller of the turntable is from 1 to 9999;
- the ratio between the frequency of rotation of the bladed propeller and the frequency of the output signals of the turntable is 1:1;
- the presence of a turntable signal converter;
- two mounting options: on a rod or on a cable using a load.
River velosity registraytor RVR-11 is designed for operation in artificial and natural rivers and cannels. The ambient temperature suitable for its operation varies from -40 to +40 °C, and the relative humidity should not exceed 98% at 25 °C. In water, the device must be used at a temperature of 1 to 30 °C and flow salinity of 0 to 1000 g/m3.
