Jinling metal tube float flowmeterfeature

Large screen LCD display, capable of displaying both instantaneous and cumulative traffic simultaneously

The upper row displays instantaneous flow rate, while the lower row displays cumulative flow rate

Instantaneous flow display range: 0.00-999.99

Accumulated traffic display range: 0.00-99999.90

Current display range: 2.86-21.00mA

Pointer angle display range: 0.00-90.00 °

Environmental temperature display range: -50 to+150 ℃

Cumulative small signal cutoff range: 0.00-1.00 (equivalent to 0-100%)

1. The instantaneous flow and cumulative flow units can be set arbitrarily;

2. Upper row switchable display: instantaneous flow rate, loop current, cumulative small signal cut-off amount, current ambient temperature, pointer rotation angle and other information At this time, it does not affect the display of the lower row cumulative measurement;

3. The LCD can display the instantaneous flow rate under the second working condition. When ordering, the cumulative quantity can be selected from the cumulative quantity under the first working condition or the cumulative quantity under the second working condition;

4. The power consumption of the dual row LCD display is microampere level, which meets the requirements of intrinsic safety and explosion-proof;

5. Accuracy:<0.5%, temperature drift:<0.2%/10 ℃;

6. Comprehensive power failure protection function, which can save the current cumulative flow in case of power failure (with a sampling period of 0.3S for cumulative flow);

7. The transmitter can output: three wire system, 0-10mA signal, regardless of whether it has LCD display function, explosion-proof type;

8. Supports battery power supply function, using rechargeable batteries of specified models. Depending on the ambient temperature, a single charge can work normally for 3-4 months.
