Operating Instructions
Water Flow Switch
Flow Control:
This flow switch is used in liquid flow lines to monitor and control the flow of water or any compatible fluid. It is designed to handle fluids that do not harm brass or phosphor bronze materials and are not hazardous.
Paddle Control:
The flow switch operates using a paddle mechanism that detects changes in fluid flow. When the flow rate reaches a predetermined level, the paddle activates an electrical switch, providing an on/off signal.
Maximum Pressure and Temperature:
The flow switch can withstand a maximum static pressure of 10 kg/cm² and a maximum liquid temperature of 100°C, making it suitable for various high-pressure and high-temperature applications.
Electrical Specifications:
The electrical switch has a Single Pole Double Throw (SPDT) rating, operating at 220VAC with a maximum current of 15A. It uses screw terminals for secure and reliable electrical connections.
Case and Connections:
The flow switch features a durable plastic cover with a 1/2 conduit opening, providing protection for internal components. The connection is made through a 3/4″ NPT male thread, ensuring a secure fit in the pipeline.
Mounting Instructions
Proper installation of the Flow Switch is crucial for its optimal performance. Follow these guidelines to mount the flow switch correctly:
Horizontal Pipe Line:
The flow switch can be mounted in a horizontal pipe line. Ensure the switch is installed in a section of the pipe where there is a straight run of at least five pipe diameters on each side of the flow switch. This ensures accurate flow detection and reduces the risk of turbulence affecting the switch’s operation.
Vertical Pipe Line:
The flow switch can also be mounted in a vertical pipe line. Ensure the switch is installed in a straight section of the pipe, following the same guidelines for a straight run of at least five pipe diameters on each side.
Tee or Welded Half Coupling:
For installations in a tee or welded half coupling, ensure the flow switch is securely mounted and properly aligned with the flow direction. This helps maintain accurate flow detection and reliable switch operation.
Adjustment Instructions
The “Ji” Japsin Instrumentation Flow Switch features sealed adjustments that are not field adjustable.
