LS45A flow meter, LS452 flow rate measuring instrument, LS full series flow meter

>LS45A - This instrument adopts novel electronic components, non-contact measurement of flow rate and flux, compact and beautiful size, reliable performance, high sensitivity, good sand resistance, corrosion resistance, no disassembly and cleaning, large measurement range of flow rate, and convenient use. It is an ideal measurement instrument for industrial wastewater discharge channels, agricultural irrigation channels, streams, rivers, and laboratories to measure flow velocity, flow rate, and instrument.

2、 Main technical indicators

1. Speed measurement range: 0.015-3.5m/s.

2. Working water depth: 0.05-3 meters. (Due to the length limitation of the signal line, if the water depth exceeds 6 meters, additional extension lines, sealed joints, and extended measuring rods must be purchased from the factory.)

3. Working temperature: -10 ℃ to+45 ℃.

4. Flow rate and flow calculation: The HR-2 flow meter is used for direct reading.

5. The relative mean square error of the entire instrument is ≤ 2%.

6. Number of signals per revolution of the instrument: four.
7. Signal reception and processing: HR-2 flow meter measuring instrument.

1、 The purpose and characteristics of the instrument

The HR type measuring instrument is a secondary instrument that is matched with the flow meter produced by our factory, which uses Hall elements as rotor output signals. It can process, calculate, and display multiple flow rate signals output by this type of flow meter for one revolution. Suitable for irrigation areas, industrial wastewater discharge channels, hydrology, and field water resource measurement. This instrument is portable, with the characteristics of small size, light weight, easy operation, and economic practicality.



2、 Main technical indicators

1. Flow measurement range: 0-9.999m/s;

2. Flow measurement duration: 20 seconds, 50 seconds, 100 seconds, or any range from 1 to 999 seconds;

3. Measurement digits: four significant digits;

4. Measurement error: ≤ 0.2% (excluding flowmeter error);

5. Flow meter signal: Number of signals: 1 to 4; Signal level: Low level ≤ 0.7V; High level ≥ 3V; Pulse width: ≥ 1ms;

6. Display method: Query method, displaying content such as time (t-X X. X X. X X), K value (=0. X X X X), C value (C-0. X X X X), duration T set value (- t - X X X), flow rate (U-X X X X), measurement duration signal N (X X X. X X X X X), etc.

7. Parameter setting and saving: adjustable time and set parameters such as K value, C value, T value, etc. The set parameters can be saved for a long time in a power-off state.
