Bosch 602819 Flow-through Sensor

Product Description

The BOSCH 602819 is a flow-through sensor designed to detect and monitor fluid or water flow within a system. This type of sensor signals the control board when flow is present or interrupted, allowing the system to respond accordingly and prevent operation under unsafe or no-flow conditions. It is a precision-fit component intended for installation by licensed plumbing or HVAC technicians familiar with hydronic or appliance-based water flow systems.

Flow-through sensors of this type are commonly used in residential and light commercial applications including water heaters, boilers, and hydronic heating systems. The sensor is installed inline with the water supply or circulation path and communicates with the unit control system to verify adequate flow before enabling heating or other downstream functions.

Key Features

• Monitors fluid flow and signals the system control board to enable or disable operation
• Designed as a direct OEM-style replacement for precise fit and reliable function
• Supports safe operation by preventing activation under no-flow or low-flow conditions
• Compact inline design suited for integration into existing plumbing or appliance connections

Compatibility

Designed as an OEM-style replacement flow-through sensor for BOSCH water heating or hydronic appliance systems requiring this sensor type.

Installation Notes

Installation should be performed by a qualified plumbing or HVAC technician. Shut off the water supply and depressurize the system before removing or installing the sensor. Ensure all connections are leak-free before restoring water supply and returning the system to operation. Follow applicable local plumbing codes and the equipment manufacturer's service documentation throughout the procedure.
