LSH10-1A TypeHandheld Ultrasonic Doppler Flow Velocity Meter

1. Instrument Introduction

The LSH10-1A handheld ultrasonic Doppler flow velocity meter is a portable flow measurement instrument designed for easy carrying and simple operation. It is an ultrasonic flow meter based on the principle of the ultrasonic "Doppler effect." Using ultrasonic technology to detect flow velocity, the measurement point is in front of the device, without disturbing the flow field. It offers high measurement accuracy, linear flow measurement, and can measure both instantaneous and average flow velocities. With no moving parts, it is resistant to silt blockage and aquatic weed entanglement, and the probe is robust and durable.

Application: Widely suitable for measuring flow velocity and water temperature in hydrology, water conservancy, open channels, water supply and drainage, aquaculture experiments, laboratory research, mining, and other scenarios. It can also perform flow rate measurements.
