MCDONNELL & MILLER FS5-3/4 114760 Switch Liquid Flow, 3/4 MNPT, 150 Psi

McDonnell & Miller FS5-3/4 liquid flow switch detects and signals lack of flow, preventing equipment damage and maintaining system efficiency. This switch alerts operators to potential issues such as low flow or pump failure, allowing for timely intervention to prevent costly downtime and damage to equipment.

Working Mechanism:

• McDonnell & Miller FS5-3/4 liquid flow switch operates by detecting the flow of liquid through the system. As the liquid passes through, it engages a paddle mechanism inside the switch. This movement triggers a switch, signalling the flow status.
• If the flow rate falls below the set point, the switch changes state, sending a signal for necessary actions. This mechanism allows for precise monitoring and control of liquid flow.

Features:

• This liquid flow switch features brass housing for durability and has a 3/4 inch NPT connection.
• It is designed for inline installation, minimising space requirements and the impact on system line pressure.
• This liquid flow switch can be operated at temperatures ranging from 32 to 250 degrees F.
• It is equipped with an SPDT switch and wetted materials including brass, Buna-N and EPDM.
