Product details
LXF-50-200 Bulk Water Meter

                                     Combination water meter

MODEL: LXF-50

MODEL: LXF-80-200

This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.



● Application

◆ For measurement of high flows of cold potable water passing through the pipeline.

● Features

◆Wide measuring range: From Qmin of the small caliber water meter to Qmax of the large caliber water meter

◆ As a dry meter, deposits in the register are avoided. This ensures a clear reading in long term service.

◆The main register may rotate more than 360 degrees for easily reading in any position.

◆ Low head loss.

◆ Lower starting flow.

◆ Novel structure, simple maintenance.   

◆Can be equipped with reed switch option.

◆Particularly suited in commercial, institutional places of assembly and facilities with fluctuating usage and flow rates.

● Working principle

◆A changeover spring valve diverts flow to the appropriate meter, opening or closing according to pressure variations by changes in flow rate.

◆At low flow rate, the changeover valve closes and only the small meter in operation 2 water flows through the bypass meter, and the usage is recorded on its register.

◆When the flow rate increases, pressure is exerted on the large meter, until the flow rate reaches approximately one half the capacity of the bypass meter.

At this point, the drop in pressure causes the valve to open 1, and water flows through both the main meter and bypass meter, and the overall consumption is read by combining the main and bypass registers.

◆When flow is decreasing, the process in reversed. The valve is closed and water flows through the small meter.

● Construction

◆The meter model LXF-50-200 combines a large caliber water meter (model LXLC-B) on the main line, a small water meter (model LXSG) on the bypass line, and a flow changeover valve.

● Working condition

◆Water temperature: ≤50℃

◆Water pressure:≤1.6Mpa

● Maximum permissible error
◆ In the lower zone from Qmin inclusive up to but excluding Qt is±5%b)

In the upper zone from Qt inclusive up to and including Qs is ±2%

INDICATION

◆Cubic meter(m3)

● Installation

◆The meter must be installed with the direction of the flow as indicated by the arrow cast in the meter body.

◆A horizontal position with the register face upwards is recommended.

◆The meter must have 10 diameters straight pipe ahead of the meter and 5 diameters straight pipe after to insure proper flow through the meter.

◆The valves must be installed in the front and the back of the water meter.

● Attachment

◆With every water meter, there will be two flange gaskets.

◆If you need the connecting flanges(two pieces), please specially request that.
