Flow Indicators / Controllers

2 products

Flow indicators and controllers are versatile devices designed to monitor, regulate, and display flow rates in various industrial processes. They provide operators with essential data for system optimization, helping reduce downtime and improve operational efficiency. These instruments are commonly used in water management, oil and gas, and chemical processing industries, where maintaining consistent flow rates is critical for safety and productivity.

Frequently Asked Questions

A flow indicator provides a real-time visual or digital display of the current liquid or gas movement within a system. In contrast, a flow controller features internal relays or output signals that can automatically open or close valves or adjust pump speeds based on pre-set flow rate thresholds.

Yes, many models in this collection are specifically designed for batching applications, allowing operators to program a specific volume of liquid to be delivered. Once the target amount is reached, the controller triggers a solenoid valve or pump to stop the flow, ensuring high accuracy in chemical mixing and food processing.

The indicators are designed to be highly versatile, accepting standard industrial inputs such as pulse signals from turbine meters or 4-20mA analog signals from electromagnetic transmitters. This compatibility allows them to be used as a centralized display for a wide variety of third-party flow sensing hardware.

The range includes robust industrial units with specialized enclosures designed to operate in extreme conditions or wash-down areas. Depending on the model, they can be supplied with high-ingress protection ratings (IP65/IP67) to ensure reliable performance in the presence of moisture, dust, or heat.

Flow controllers act as a critical safety barrier by monitoring for "no-flow" or "high-flow" conditions that could indicate a pipe burst or pump failure. When these conditions are detected, the controller can immediately shut down the system or trigger an audible alarm to prevent equipment damage or hazardous leaks.

Professional calibration is essential to ensure the controller accurately interprets the data it receives from the sensor and triggers outputs at the correct moments. HK Calibrations provides traceable calibration services to verify the entire loop, ensuring your automated flow processes remain precise and compliant.
