GH-2080 portable open channel flowmeter

purpose

The open channel flowmeter is used in conjunction with the open channel weir groove, using ultrasonic waves to pass through the air and measure in a non-contact manner,Suitable for reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, farmland irrigation, water management, water resources, etcParshall flumeMeasurement of flow in open channels with rectangular troughs, triangular weirs, and equal width weirs.

Mainly used to measure the flow rate of sewage discharge outlets of sewage plants, enterprises and institutions, and urban sewers. Due to the fact that it does not come into contact with fluids during measurement, it has higher reliability than other forms of measurement instruments in the presence of contaminated and corrosive liquids.

This instrument has data storage function. The stored records can be viewed through the buttons on the instrument panel, printed with a Bluetooth printer, and exported from a USB drive.

Performance Characteristics

◈Non contact measurement, the sensor does not come into contact with the fluid and is not corroded or contaminated by sewage;

◈Adopting imported sensors and ABS shell fully sealed structure, it is resistant to alkali, corrosion, and has stable measurement data comparison process and result output. The wider the application range, the more accurate the measurement;

◈Direct measurement of flowing water surface: The sensor directly measures the liquid level of the flowing water surface without using a static water well, which can prevent the blockage of the connecting pipe caused by suspended solids, sediment, etc. in the sewage due to the use of a static water well, resulting in inconsistent water levels between the static water well and the measuring weir tank, or false liquid levels due to winter icing, leading to flow measurement errors;

◈Real time display of measurement comparison curve during flow meter comparison measurement, allowing for intuitive observation of real-time liquid level changes. Real time curves can facilitate users to observe real-time changes in liquid level and flow rate, making it easy to grasp the trend of changes during this time period and understand the amount of wastewater discharged;

◈By setting instrument parameters through the keyboard, it can be used with various measuring weirs and tanks. To adapt to different application conditions such as surface open channels and underground culverts;

◈Optional installation of positioning system, which can display the latitude and longitude of each comparison measurement location on the comparison measurement report, facilitating the tracking and authentication of comparison results.
