What are the advantages of the turbine flowmeter in the measurement of small flow, no matter what the meter in the measurement of flow have a range ratio, both the lower limit and the upper limit of the requirements. Turbine flowmeter is no exception. You can look at the table:

Turbine flowmeter according to customer needs to choose their own products, turbine flowmeter with pulse output, current output, the lithium battery site display, 24 volt power supply field display remote type.

1, turbine flowmeter pulse output type

Working voltage: +12VDC or +24VDC two (customer order must be selected before a power supply). Signal transmission distance: less than 250 meters. Output signal: square wave signal amplitude: +12VDC power amplitude is about 10V+24VDC amplitude is about 20V power amplifier and turbine flow sensor installation: connect the M16 * 1.5 threads, the installation of turbine flow sensor, the amplifier is screwed to the turbine flow sensor, hand twist the feeling after the end amplifier with tight lock nut. Wiring: pulse output amplifier external lead three, red, white and shielding. The red line is connected with the positive power supply, and the white line is a pulse output which is connected with other display devices or equipment.

2, turbine flowmeter current output type

Working voltage: +24VDC external power supply (two wire) output signal: 4~20mA or 1-5V, 4mA corresponds to zero flow turbine flow sensor, 20mA for maximum flow turbine flow sensor, see the nameplate flow range of turbine flow sensor. Signal transmission distance: less than 250 meters. Installation: after the installation of the turbine flow sensor, the amplifier is screwed to the turbine flow sensor connector (M16 x 1.5 thread), with the hand to the amplifier has been locked in the end of the lock nut tight. Wiring: 4~20mA output amplifier external leads to red and white lines. The red line is the power cord and the white line is the signal line.

3, turbine flowmeter lithium battery on-site display type

The utility model relates to an intelligent flowmeter, which is a novel flowmeter display instrument which is designed by adopting the advanced single-chip microcomputer technology, and is matched with a flow sensor (such as a turbine, a vortex) which is output by a pulse signal. Can display instantaneous flow and cumulative total. Cumulative flow: eight digits, the decimal point behind the 3 digits. Instantaneous flow rate: six digits, can show the change per liter. Display accuracy: + 1 display units. Signal output: pulse output: 1~3000Hz for external +12~+24VDC power supply current output: 4~20mA for +24VDC power supply (two wire) built-in 3V lithium battery parallel power supply. When the voltage is lower than 2.7V, there is an indication of undervoltage. Small signal removal.
