System Introduction
The JZYG-LJ20 rotary propeller flowmeter is a large-scale river hydrological speed measurement instrument that uses the principle of magneto electric conversion, non-contact measurement, multiple signal acquisition, high sensitivity, good waterproof and sand prevention performance, and a compact instrument structure. It can be used for various high, medium, and low flow velocity measurements in water bodies such as rivers, lakes, channels, and reservoirs. It can also be used for high-speed and ultra high speed measurements in power plant pressure pipelines and certain scientific experiments.
This product complies with technical standards such as GB/T11826-2002 "Spiral Flow Meter".

Features and Characteristics
1. Sunshine Smart Cloud Platform
Real time cloud monitoring and storage of device data 24/7. Users do not need to monitor data online. Data collection and calculation are completed by the cloud platform on the server side. They only need to turn on the monitoring system when they need data, log in to the platform, and synchronize with the cloud data platform to view real-time and historical data information on both PC and mobile devices.

Customers who purchase our company's monitoring system products can access the cloud platform for free and provide free data services

2. The dynamic sealing device of the rotating shaft has good performance and can effectively slow down the water ingress into the bearing oil chamber, ensuring the normal operation of the bearing. Under normal working conditions, the bearing should be cleaned and oiled once a year.
3. Water can be used instead of gasoline as a sealing fluid for the front stage rotary sealing device, as well as a general component detergent, making cleaning easy.
4. The axial working clearance of the rotating support system is a non adjustable structure, and components such as bearings and inner sleeves are randomly replaced to ensure clearance values and instrument sensitivity. Assembly, maintenance, and overhaul are all very convenient.
5. The signal components adopt advanced magnetic sensitive reed switch electronic switches, and the devices are selected from internationally renowned high-quality products. The signal quality is good, the performance is stable, the work is reliable, and the service life is long.
6. The signal component adopts a dual magnetic excitation structure, with sensitive action, low resistance, stable performance, and reliable operation.
7. The magnetic sensitive reed switch of the signal component is installed outside the oil chamber, with fast and easy loading and unloading, good universality, and no need for adjustment.
8. The calculation method for low-speed measuring points adopts the low-speed straight line formula, which is easy to calculate.
9. The series products have a high degree of standardization, with modular and universal instrument components, making production, use, maintenance, repair, and management very convenient.
10. Diversified measurement installation methods: fixed installation of measuring rods, self-adjusting installation of suspension suspension shafts, installation of large lead fish head columns in hydrological cable channels.
11. There is also a propeller with optimized propeller structure parameters, which has good diagonal flow response characteristics.
