Suitable for measuring the pressure of liquids, gases, or steam, it features on-site switch control for interlocking, real-time local display of pressure values, and remote signal transmission to the control system. Pressure setpoints and operating modes can be easily configured via button operation. The switch output is a passive dry-contact signal (SPDT). Common applications include: 1. Start/stop control for air compressors; 2. High- and low-pressure alarms in pipelines, triggering interlocked pump start/stop sequences, etc. The pressure switch directly outputs a switching signal, delivering functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. This product boasts the following key features:
●Multi-channel digital output
● Display pressure values directly on-site
● Multiple alarm methods can be set
● Set action values with buttons

LPS-N1C Smart Differential Pressure Switch
Suitable for measuring the pressure difference of liquids, gases, or steam, it features on-site switch control for interlocking functions, real-time display of pressure values, and remote signal transmission to the control system. Operation via buttons allows users to set the actuation value and mode. The switch output is a passive dry-contact signal (SPDT). Common applications include: 1. Preventing clogging by monitoring the pressure differential before and after filters; 2. Controlling pressure differences in conveying pipelines. This pressure switch directly outputs a switching signal, offering functionality equivalent to that achieved by combining a pressure transmitter with PLC/control instrumentation for switch-based control.

The LF-19X wedge flowmeter is a flow measurement instrument designed based on the differential pressure principle. Its core component is a V-shaped or wedge-shaped throttling element, primarily used to address the challenges of measuring flow rates for "dirty fluids" such as high-viscosity liquids, fluids containing solid particles, and substances prone to scaling. This makes it an ideal solution that overcomes the common issue of clogging found in conventional differential-pressure flowmeters like standard orifice plates and Venturi tubes. The product features the following characteristics:
● Wide applicability: Particularly adept at measuring high-viscosity or impurity-laden fluids such as crude oil, asphalt, pulp, and mud; also suitable for use with conventional gases and liquids.
● Strong anti-clogging capability: The wedge-shaped throttling element features no sharp dead corners between itself and the pipeline, preventing solid particles or viscous media in the fluid from easily accumulating, thus extending the maintenance cycle.
●Low installation requirements: The length of the straight pipe sections required upstream and downstream is significantly shorter than that for standard orifice plates (typically just 5D upstream and 2D downstream, where D represents the pipe diameter), saving valuable installation space.
