Radar flow velocity monitoring system

Product Introduction

The HM-LS radar flow velocity monitoring system is a new generation non-contact flow velocity measurement product launched by Shandong Hengmei Electronic Technology Co., Ltd. The instrument adopts K-band planar microstrip array antenna, which is energy concentrated and low-power consumption; Integrated vertical angle compensation, flow rate filtering algorithm, signal strength detection, RS485/RS232 communication, wireless communication and other functions; When using non-contact radar flow measurement method for speed measurement, the equipment is not corroded by sewage, not affected by sediment, and less affected by water damage. The civil construction is simple, easy to maintain, and personnel safety is guaranteed. The special antenna design makes the power consumption extremely low, greatly reducing the power supply demand. Not only can it be used for regular flow velocity monitoring, but it is also particularly suitable for undertaking urgent, difficult, and dangerous observation tasks.

Product features

(1) Non contact, safe with low damage, minimal maintenance, and unaffected by sediment.

(2) Capable of measuring under high flow velocity conditions during flood periods.

(3) It has anti reverse connection and lightning protection functions.

(4) The system has low power consumption and is generally powered by solar energy to meet the needs of current measurement.

(5) Multiple interface methods, including both digital and analog interfaces, facilitate system integration.

(6) Wireless transmission function (optional), which can wirelessly transmit data beyond 3.5km.

(7) The speed measurement range is wide, and the measurement distance can reach up to 40m.

(8) Multiple triggering modes: cycle, trigger, query, automatic.

(9) The installation is particularly simple, and the amount of civil engineering is very small.

(10) Fully waterproof design, suitable for outdoor use.
