1、 Product Introduction
The radar current meter is a new generation non-contact measurement product for flow velocity launched by Shandong Hengmei Electronic Technology Co., Ltd. The instrument adopts a K-band planar microstrip array antenna, with concentrated energy and low power consumption; Integrated with functions such as vertical angle compensation, flow velocity filtering algorithm, signal strength detection, RS485/RS232 communication, wireless communication, etc; When using non-contact radar flow measurement for speed measurement, the equipment is not corroded by sewage, is not affected by sediment, is less affected by water damage, has simple construction, is easy to maintain, and ensures personnel safety. The special antenna design results in ultra-low power consumption, greatly reducing power supply requirements. Not only can it be used for regular flow rate monitoring, but it is also particularly suitableUndertake urgent, difficult, dangerous and heavy observation tasks together.
