Flowalarm

Flowalarm is a monitoring system or device designed to detect abnormal fluid flow in piping or channels and trigger alerts to prevent process faults, equipment damage, or product quality issues. It can be a dedicated instrument or part of a broader process control system, such as SCADA or PLC networks.

Operation relies on a flow sensor to provide real-time measurements. Common technologies include magnetic, ultrasonic, turbine, and Coriolis meters. A controller compares measured flow against configured thresholds or monitors rates of change. Alarms may incorporate deadband or hysteresis to reduce nuisance alerts.

Alarm actions may be local (audible or visual indicators) and remote (SCADA alarms, email, SMS, or push notifications). Automatic responses can include shutting valves, stopping pumps, or initiating bypasses, depending on safety and workflow requirements. Data logging and event sequencing support audit trails and post-incident analysis.

Design considerations include sensor placement, pipe diameter, temperature and pressure effects, and environmental conditions. Reliability features such as redundancy, fault-tolerant power, and robust enclosures are important in hazardous or remote locations. Interoperability with standards such as Modbus, OPC UA, or DIN/IEC protocols enhances integration.

Applications span water distribution, wastewater, chemical processing, oil and gas, and food and beverage. Flowalarms help ensure continuous operation, conserve energy, detect leaks or blockages early, and support regulatory compliance through traceable alarms and response records.
