LS1206B rotary flow meter for hydrological measurementMeasurement principle:

This instrument is designed based on the principle of velocity area method for open channel flow measurement. By measuring the velocity, the flow rate Q=V · S (S is the cross-sectional area) can be obtained

1. Flow rate measurement:

When measuring flow velocity, the propeller rotor flowmeter is driven by hydraulic power to rotate, and the built-in signal device generates a rotational speed signal. The flow velocity is calculated using the following formula:

V＝———————— ＋ C（m/s）

In the formula: V: Average flow velocity during the flow measurement period（m/s）

K: Hydraulic pitch of propeller blade

C: Constant of flow meter

T: Duration of flow measurement (unit: S)

N: Number of signals during time period T

When using this instrument, K and C are constants. When measuring flow, as long as T and N are measured, the flow velocity can be calculated.

2. Calculation of traffic:

Flow measurement is based on the velocity area method of open channel flow measurement, which first measures the velocity and then multiplies it by the cross-sectional area to obtain the flow rate.

Computer online operation(This function is not available when there is no requirement for ordering)

Firstly, connect the measuring instrument to the communication port of the computer using a dedicated communication cable. Open the computer and enter the WINDOWS platform - Programs - Accessories - Communication - Hyperterminal. Set the baud rate to 2400, the communication bit to 8 bits, the stop bit to 1 bit, the parity check to none, and the flow control to software mode. Select the correct communication port, connect the signal power line of the measuring instrument, and start the current measurement. After each flow measurement is completed, the measuring instrument automatically sends a set of data to the computer screen for display.

K=7800 C=0.050 T=0106.5 N=0015 V=0.160

K=7800 C=0.050 T=0108.4 N=0016 V=0.165
