Instrument Introduction
The LSH10-1A handheld ultrasonic Doppler flowmeter is an ultrasonic flowmeter made using the principle of ultrasonic "Doppler effect". Use ultrasonic technology to detect flow velocity, with the measurement point in front of the body, without damaging the flow field; High measurement accuracy, linear flow measurement, capable of measuring instantaneous flow velocity and average flow velocity; No rotating parts, not afraid of mud blockage and water grass entanglement, the probe is sturdy and durable.
■ Performance characteristics
High measurement accuracy, wide range, capable of measuring weak current and strong current;
● Sensitive induction, high resolution, not limited by start-up flow rate;
Fast response speed, capable of measuring instantaneous flow velocity and average flow velocity;
Measure linearity without the existence of calibration curves for K and C values;
There are no mechanical rotating parts, and there are no problems such as sediment blockage or entanglement with water plants or debris. It is most suitable for measuring in rivers with high suspended sediment content and floating objects such as water plants.
■ Function Introduction
Mini handheld host is convenient for users to carry and measure observation;
● Large screen LCD display with continuous background light function;
Built in complete clock, convenient for users to calibrate and check time;
Equipped with data reading software to achieve data storage, printing, and output functions;
Real time display of instantaneous flow velocity and average flow velocity;
The measurement modes are divided into automatic measurement and manual measurement, meeting the needs of different occasions.
