The HJ-UT-F Series Open-channel Flowmeter is a high-performance ultrasonic time-difference method open-channel flowmeter based on the Huaju HJ-UT platform.

The transducers of this series of flowmeters can be installed either in a split-mount or integrated-mount configuration. For split-mount installation, orders can be placed without waiting for the completion of detailed design; it only requires confirmation of the detailed installation dimensions prior to formal installation, which greatly improves delivery efficiency. The equipment installation does not need to alter the shape of the existing channel and involves minimal civil engineering work, making it particularly suitable for the accurate flow measurement of various large and medium-sized main canals and branch canals in irrigation districts.
