LXF-50～150

Measurement Requirements

Temperature class: T30

Water pressure class: MAP10 or MAP 16 on request.

Pressure-loss class: △p63

Sensitivity to the irregularity in the upstream velocity fields class; U10

Sensitivity to the irregularity in the downstream velocity fields class; D5

Maximum Permissible Error

a) In the lower zone (Q1≤Q﹤Q2) ±5%

b) In the upper zone (Q2≤Q≤Q4) ±2% 

Applications: to record the total volume of water passed through the water pipelines.

Characteristics: 

In-line type of water meter comprising one large flow rate meter，one small flow rate meter and a change over device that，depending on the magnitude of the flow rate passing through the meter. Automatically directs the flow through either the small or large meter or both. So the flow rate range of the meter compared with other types of meters is more widely. It is easy for maintenance for its removable measuring unit and directly magnetic coupling transmission. For the small meter，the wet dial register type and the liquid-sealed register type are on option.

Note:

1. The water meter complies with the standard of<<GB/T 778.1-3-2007>> (ISO 4064-1-3:2005, IDT）.

2.Two types of registers for the large meter for option, the plastic cover register. Type: P and glass cover register. Type: M
