The DOF6000 series flowmeter consists of Flow calculator and the Ultraflow QSD 6537 sensor.
The Ultraflow QSD 6537 Sensor is used to measure water velocity, depth, and conductivity of water flowing in rivers, streams, open channels and pipes.
When used with a companion Lanry DOF6000 Calculator, flow rate and total flow can also be calculated.
The flow calculator can calculate the cross-sectional area of partially filled pipe, open channel stream or river, for stream or river, with up to 20 coordinate points describing the river’s shape of cross section. It is suitable for various applications.
Ultrasonic Doppler Principle in Quadrature Sampling Mode is utilised to measure water velocity. The 6537 Instrument transmits ultrasonic energy through its epoxy casing into the water. Suspended sediment particles, or small gas bubbles in the water reflect some of the transmitted ultrasonic energy back to the 6537 Instrument’s ultrasonic receiver instrument that processes this received signal and calculates the water velocity.
