Murphy天然气压缩机洗涤罐液位控制系统 MLS Liquid Level Switch
FW Murphy MLS Scrubber Liquid Control System
Automatic Level Control for Gas Scrubber Applications
FW Murphy Gas Compressor Scrubber Level System
Murphy MLS系列液位开关采用浮子激活，用于操作电气SPDT簧片开关，用于向报警器、控制器或PLC发出信号/导频信号，以指示高液位。MLS直接连接到气体洗涤器壁上，可与FW Murphy焊环或FW Murphy外部浮子室一起使用。MLS 系列提供 1-1/2 和 2 英寸两种尺寸。NPT 型号，带或不带测试按钮。
测试按钮测试浮点函数;完整的机制，包括簧片开关的磁激活;以及从开关到控制面板的接线。
MLS专为恶劣气体压缩机洗涤器应用而设计。
注意： 不建议用于氢气应用。
额定工作压力为 2000 psi （13.8 MPa） [138 bar]。
注意：不要超压。如果暴露在超过额定压力 （2000 psi） 的压力下，不锈钢浮子可能会变形。
这可能会影响比重和整体操作。
MLS 系列液位开关提供带或不带测试按钮，提供 1 1/2 英寸和 2 英寸 NPT 型号。它们直接连接到气体洗涤器壁上，可与 FW Murphy 焊环或 FW Murphy 外部浮子室一起使用。
- 干净的磁铁设计几乎消除了磁铁上铁屑的堆积

MLS 系列液位开关
MLS系列液位开关是浮动激活的，用于操作SPDT簧片开关，用于向信号器、控制器或PLC指示高液位的报警/引导信号。MLS直接连接到气体洗涤器壁中，可与FW Murphy焊接套环或FW Murray外部浮子室一起使用。MLS系列有1-1/2和2 in.NPT两种型号，可带或不带测试按钮。测试按钮测试浮动功能；包括簧片开关的磁性激活的完整机构；以及从开关到控制面板的接线。
MLS Series Liquid Level Switches are float activated to operate an electrical SPDT reed switch for annunciation/pilot signal for indication of high level to an annunciator, controller or PLC. The MLS connects directly into the gas scrubber wall and can be used with an FW Murphy weld collar or FW Murphy external float chamber. The MLS Series is available in both 1-1/2 and 2 in. NPT models and with or without the test button.
The test button tests for float function; the complete mechanism including the magnetic activation of the reed switch; and the wiring from the switch to the control panel.
The MLS is designed for harsh gas compressor scrubber applications.
NOTE: Not recommended for hydrogen gas applications.
Rated for 2000 psi (13.8 MPa) [138 bar] working pressure.
NOTE: DO NOT OVERPRESSURE. The stainless-steel float may be deformed if exposed to pressure beyond rated (2000 psi).
This can affect specific gravity and overall operation.
Liquid Level Switches
Available with or without the test button, the MLS Series is available in both 1 1/2 inch and 2-inch NPT models. These connect directly into the gas scrubber wall and can be used with an FW Murphy weld collar or FW Murphy external float chamber.
Clean magnet design virtually eliminates iron filing accumulation on the magnet
Seal-free construction
ANSI/ISA 12.27.01 compliant (Single Seal)
Operates in 0.50 specific gravity or heavier fluids
304 cast equivalent SS body and 304 SS float
Trip on rising and falling without need to rotate body
Electric model only available

Scrubber Level System Tools
Scrubber Level Control System Emissions Calculator (.xls, 613KB)
The SLS Emissions Calculator allows you to plug in application information, such as ambient temperature, dump frequency, dump rate and supply pressure, and provides the total system emission of gas per hour.
DVU Selection Guide (.zip, 327KB)
The DVU Selection Guide selects the appropriate dump valve model for the user using a series of calculations. This calculation is obtained after the user inputs application information such as diameter of vessel, duration of dump cycle, vessel pressure and pressure at outlet of DVU.
New Product Release: MLS
Murphy is proud to announce that effective immediately, the MLS is officially approved for production release.
Purpose
The MLS Series connects directly into the gas scrubber wall and can be used with a Murphy weld collar or Murphy external float chamber and is available in both 2”NPT and 1-1/2” NPT models.
The MLS Series can replace many existing electric liquid level switches currently being offered by Murphy including the L1200 and LS200. The Stainless Steel construction makes the MLS a perfect single model for all applications without the need for special part numbers or multiple items stocking.
Description
The MLS is typically used to detect a high liquid level in a gas scrubber vessel and annunciate/pilot a signal for alarm/shutdown of an engine or electric motor.
Its primary features/benefits are:
- Seal free, stainless steel construction
- Clean Magnet Design
- Trip on rising or falling without need to rotate the body
Agency Approvals:
- CSA C/US Class I, Div. 1 Grps. B, C & D
- NACE MR0175 compliant
- Canadian Registration Number
- MLS-020, 0F01476.2
- MLS-015, 0F12013.2
