Handheld radio current meter

　　Handheld radio current meterThe all-weather working ability of microwave radar is not affected by temperature gradients, pressure, air density, wind or other meteorological environmental conditions, and can work stably all day long. Highly portable and compact in design, typically weighing less than 1kg, supporting handheld measurement or tripod installation, making it easy for a single person to operate. Easy to operate, equipped with a Chinese interface and guided operation, one click can achieve automatic correction of horizontal and vertical angles, reducing training costs. Built in large capacity lithium battery for data storage and transmission, capable of continuous operation for more than 10 hours; Support USB interface for exporting data, facilitating subsequent analysis and processing; Some models also support Bluetooth connection to printers or mobile terminals for wireless data transmission.

1、 Product Introduction:

　　Handheld radio current meterThe instrument uses K-band radar for non-contact velocity measurement of rivers, sewage, mud, and oceans. It has the characteristics of small size, handheld operation, battery power supply, and easy use. It is not corroded by sewage or disturbed by sediment during use, and can perform non-contact measurements within a measurement range of less than or equal to 100 meters, ensuring the safety of the measurer. The instrument includes a highly sensitive planar narrowband radar probe and angle meter, which do not require any settings. With just one click operation, automatic correction of horizontal and vertical angles and correction measurement of flow velocity can be achieved, making it very convenient to use.

2、 Application areas:

Channel flow velocity monitoring, river flow velocity monitoring, sewage flow velocity monitoring, ocean flow velocity monitoring, railway bridge construction flow velocity monitoring; Emergency monitoring of flood prevention and control sites, monitoring of sewage discharge, and other occasions that require on-site measurement.
