• Loop-Powered Convenience: Operates entirely on the 4-20mA current loop from compatible flowmeters, eliminating the need for separate power supplies.
• Flowmeter Compatibility: Works seamlessly with various flowmeter types like differential pressure, magnetic, and vortex, offering flexibility for your application.
• Intrinsically Safe: Certified for safe use in hazardous areas according to European and North American standards, ensuring operator safety.
• Programmable Accuracy: Tailor the instrument to your specific flowmeter with options for linear or square law input relationships, programmable span, cut-offs, and conversion factors. Non-volatile memory ensures all settings and totals are retained even during power outages.
• Alarms and Scaled Outputs: Built-in high and low flow rate alarms provide real-time monitoring. Additionally, the high alarm output can be programmed to generate a scaled pulse signal proportional to the total flow volume, enabling further analysis or integration with control systems.
• Rugged Construction: The 202A boasts a watertight IP67 (NEMA 4X) polycarbonate enclosure, making it resistant to harsh outdoor conditions.
• Mounting Flexibility: Comes standard with a wall mounting bracket, with a 2-inch pipe mounting bracket and panel mount option available for versatile installation.

• Standard: Powered by long-life lithium batteries, ideal for remote locations or applications without AC power.
• Optional Loop Power: Operates on the 4-20mA loop current from compatible flowmeters, eliminating the need for separate power supplies.
• DC Power: Can be powered from a 9-28 Volt DC supply for added flexibility.
• Intrinsically Safe Option: Available for safe use in hazardous environments, with certifications covering all input and output circuits.

• Enclosure Options: Choose between a lightweight polycarbonate or a heavy-duty aluminum housing, both rated for harsh outdoor environments (IP67).
• Mounting Versatility: Wall, pipe, or direct flowmeter mounting (turbine) are all possible. The polycarbonate version even offers a panel mount option.

• Customization: Program K-factor (conversion factor), decimal point placement, filter constants, and timebase to match your specific flowmeter and desired level of detail.
• Unit Display: Select engineering units (e.g., gallons per minute, barrels) for clear and easy interpretation of flow rate and total values.
• Hazardous Area Benefit: Contrec's unique magnet access strip allows reconfiguration without opening the enclosure, minimizing downtime during maintenance in hazardous locations.

• Frequency-to-Current Conversion: The loop-powered version excels at converting low-frequency pulse signals from positive displacement or turbine flowmeters into a stable and accurate 4-20mA output.
• Non-Linearity Correction: Enhance measurement precision with 10-point correction for K-factor variations across different flow rates. (Note: Increases display update rate in battery-powered models)
