VFS 114 Gas Geyser Inline Pressure Sensor for Water Flow Detection

The VFS 114 Gas Geyser Inline Pressure Sensor from Vachan is a compact and dependable sensor designed to detect water pressure and flow in gas geysers, instant water heaters, and domestic hot water systems. Installed directly in the water line, it monitors water movement and sends a signal to the control system, ensuring that the heating element or burner activates only when sufficient water flow is present. This improves operational safety, conserves energy, and protects the appliance from damage caused by dry operation.

Engineered with a durable polypropylene (PP) housing and sealed using PU/Epoxy potting, the VFS 114 offers excellent resistance to moisture, vibration, and long-term use in demanding environments. Operating on a low 5 VDC supply, it features a Normally Open (NO) contact, supports frequencies up to 100 Hz, and is capable of switching up to 0.5 Amp DC with a 10 W contact rating. Its compact inline construction and pre-fitted 6-inch cable with connector enable quick installation and seamless integration into OEM designs and replacement applications.

Suitable for gas geysers, instant water heaters, tankless heating systems, pressure monitoring circuits, safety interlock systems, and water flow control applications, the VFS 114 delivers precise and reliable performance. With a service life of 500,000 switching cycles and an operating temperature range of -25°C to +75°C, it provides long-lasting, maintenance-free operation. Whether used by appliance manufacturers, service engineers, or system integrators, the VFS 114 Gas Geyser Inline Pressure Sensor ensures consistent water flow detection, enhanced safety, and dependable performance in residential and commercial water heating systems.
