Loop & Process Meters

3 products

Loop process meters are compact, self-powered instruments designed to display real-time measurements directly from a 4–20 mA current loop. These meters eliminate the need for external power, drawing energy directly from the signal loop, which simplifies installation and reduces wiring costs especially in remote or hazardous locations. Commonly used for monitoring flow, pressure, level, temperature, and other process variables, loop meters offer features like dual-line displays, programmable alarms, and built-in relays for signal control or retransmission. Built for tough conditions with IP-rated front panels, they ensure visibility in bright sunlight or dimly lit areas. Ideal for industries including water treatment, chemical processing, and oil & gas, loop process meters streamline monitoring workflows while enhancing system visibility and control.

Frequently Asked Questions

A loop meter is specifically designed to measure, source, and simulate 4-20mA signals, which are the industry standard for process control. HK Calibrations supplies these tools to Australian technicians to help them troubleshoot sensors, valves, and PLCs without breaking the circuit.

While a multimeter measures various electrical values, a process meter can both measure and source (generate) precise current and voltage signals. HK Calibrations provides these advanced instruments to allow Australian engineers to simulate a sensor's output and verify that control valves or readouts are responding correctly.

Many industrial transmitters are loop-powered, meaning they don't have their own power supply. HK Calibrations stocks process meters that can provide a 24V DC loop power supply while simultaneously measuring the current, making it an all-in-one tool for field-testing isolated transmitters across Australian worksites.

In process control, a measurement error of just 0.1mA can lead to significant inaccuracies in tank levels or temperature readings. HK Calibrations offers ISO-traceable calibration at our Australian laboratories to ensure your meter’s sourcing and measuring capabilities remain authoritative and precise.

Yes, many of our high-end process meters are compatible with HART (Highway Addressable Remote Transducer) protocols, allowing for digital communication with "smart" transmitters. HK Calibrations ensures Australian technicians have the right gear to configure and calibrate modern, intelligent process equipment.
