Model | Display & output | power supply |
LWQN | Voltage Pulse, low level≤1V, high level≥5V,3-wire | DC12V-24V |
LWQ-A | Current output: 4~20mADC,2-wire | DC24V |
LWQ-B | Multi-point non-linear correction, two rows LCD indication of instantaneous flow and accumulative flow, such as: Q XXXX 4 bit instantaneous flow value(m3/h) XXXXXXXX 8 bit accumulative flow value(m3) PS: The accumulative flow value that can be cleared counts from 00.00000 to the maximum of 999999.99 automatically. The instrument coefficient and accumulative flow value can be saved for ten years without power | 3.2V10AH lithium battery |
LWQ-C | LWQ-B (Field display type) with the addition of 4-20mADC current output | DC24V |
LWQ-D | LWQ-B (Field display type) with the addition of temperature and pressure sensor Automatic compensation for different operation condition; Temperature, pressure, and battery power etc. being inquired through the switch of magnet High frequency and low frequency voltage pulse signal output and 4-20mADC 2-wire current signal output. | 3.2V10AH lithium battery |
Note: Figure 1 is the outline of temperature and pressure compensation type meter.All types of flow meter with the same diameter have identical dimension of sensors part as well as the total height of meter.
