Lanry Instruments is the professional manufacturer of flow detection instruments, provides one package service of research and development, production, marketing and after-sales services. Engaged in the production of flow instruments more than 20 years. Lanry has been equipped with advanced design capabilities and piled up a wealth of field application experience, which lays solid foundation for the commitment to the promotion and innovation of hightech system solution. The corporation has devoted to the production of flow measurement instruments with superior performance, high stability and strong reliability. 


DOF6000-P Portable Doppler Open Channel Flow Meter

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
