Executive Summary & Core Capabilities
The Cosasco Microcor M-310 / M-320 Wireless Corrosion Transmitter delivers high-resolution metal loss measurement to remote process lines without signal cables. Traditional electrical resistance (ER) technology often requires days or weeks to trend reliable corrosion rates. Microcor technology resolves metal loss to (), revealing corrosion upsets in minutes or hours.
Available in two wireless protocol versions— M-310 (ISA100 Wireless) and M-320 (WirelessHART)—the transmitter mounts directly onto the probe connection head via a compact adapter. This direct-coupling setup eliminates cable capacitance errors and minimizes installation costs.
Operational Advantages
- Detects Upsets in Minutes: Identifies acid or oxygen ingress upsets in under an hour, allowing operators to rapidly optimize chemical inhibitor dosing.
- Universal Fluid Capability: Operates reliably in dry natural gas, wet crude, water injection, and multiphase pipelines.
- Zero Trenching Costs: Wireless mesh communication cuts field deployment costs by up to 70% compared to hardwired architectures.
- Intrinsically Safe: Powered by a long-life internal battery pack certified for Zone 0 / Class I Div 1 hazardous environments.
18-Bit High-Resolution Engine
Uses an 18-bit measuring engine ( discrete counts) to track micro-ohm electrical resistance variations.
Electrical resistance is related to metal loss by:
By pairing the exposed sensing element with an internal sealed reference element, the transmitter automatically cancels out process temperature fluctuations.
