ecom UNO / ecom DP Differential Pressure Meters by ECOM (Czech Republic)

Overview

The ecom-UNO and ecom-DP are precision-engineered portable differential pressure meters designed specifically for commissioning, maintenance, and regulatory compliance verification of combustion systems, ventilation installations, and flue gas pathways. Both instruments operate on the principle of piezoresistive pressure transduction, delivering stable, repeatable measurements under dynamic field conditions. The ecom-UNO serves as a compact, single-channel reference-grade gauge optimized for rapid spot checks—ideal for measuring draft pressure across heat exchangers, burner manifolds, or gas valve differentials. Its ultra-lightweight form factor (150 g with batteries) and magnetic rear housing enable secure attachment to ferrous surfaces during hands-free operation. In contrast, the ecom-DP is a dual-sensor, multi-range instrument capable of simultaneous or independent channel measurement—enabling real-time comparison of upstream/downstream pressures or differential monitoring across parallel system branches. Its architecture supports traceable calibration workflows and integrates directly into documented safety-critical procedures such as TRGI (Technische Regeln für Gasinstallationen) tightness testing and EN 15502-compliant boiler commissioning.

Key Features

• ecom-UNO: High-resolution ±200 hPa range with 0.01 hPa resolution and ±1% accuracy; four selectable pressure units (hPa, mmH₂O, PSI, mmHg) with instantaneous conversion.
• ecom-DP: Dual independent pressure inputs supporting concurrent measurement at two distinct ranges—0–7 kPa (0.01 kPa resolution) and 0–150 kPa (0.1 kPa resolution)—both with ±3% full-scale accuracy.
• Magnetic mounting interface (ecom-UNO) and ruggedized ABS housing rated for industrial environments (IP54 equivalent).
• Intelligent data handling: Min/Max capture, manual data hold, user-adjustable damping (0–10 s), and auto-zero function for drift compensation.
• ecom-DP-specific capabilities: Programmable test sequences (e.g., step-pressure hold for gas valve leakage assessment), time-stamped internal logging (up to 10,000 records), and USB/Bluetooth-enabled synchronization via ecom-DP Logger software.
• Backlit graphical display (ecom-DP) with intuitive icon-driven menu navigation and real-time trend visualization.

Sample Compatibility & Compliance

These instruments are validated for use with dry, non-corrosive, non-condensing gases—including ambient air, natural gas (G20/G25), propane (G30), and flue gas streams with particulate loading below 5 mg/m³. They comply with essential requirements of the EU Measuring Instruments Directive (MID) Annex MI-004 for pressure measuring devices and meet mechanical and EMC criteria per EN 61326-1:2013. For regulated applications, the ecom-DP supports audit-ready documentation: all logged measurements include timestamp, sensor ID, unit, and operator-defined test tag—fully compatible with GLP and GMP-aligned record-keeping frameworks. TRGI Annex B.3.2.2-compliant test protocols (e.g., 10-minute stabilization + 5-minute pressure decay evaluation) are preconfigured and executable without external scripting.

Software & Data Management

The ecom-DP Logger desktop application (Windows/macOS) provides full bidirectional communication: download logged datasets, export CSV/PDF reports, configure device parameters (damping, auto-off, unit defaults), and define custom test templates. All exported files include embedded metadata—device serial number, firmware version, calibration due date, and user-entered site identifier—ensuring data integrity per FDA 21 CFR Part 11 principles (electronic signatures optional via third-party PKI integration). Raw measurement logs retain millisecond-level timestamps and channel-specific error flags (e.g., overrange, low battery, sensor saturation), enabling root-cause analysis during QA/QC review cycles.

Applications

• Combustion safety verification: Draft pressure across chimney liners, induced-draft fan differentials, and balanced-flue system integrity checks.
• Gas installation commissioning: TRGI-mandated tightness testing of meter outlets, riser sections, and appliance connections (0.05 bar/5 kPa hold tests).
• HVAC system balancing: Duct static pressure profiling, filter resistance monitoring, and VAV box differential verification.
• Boiler efficiency diagnostics: Primary/secondary air damper pressure drop quantification and economizer bypass characterization.
• Research & education: Controlled lab experiments involving laminar flow resistance, orifice plate calibration, and fan performance mapping.

FAQ

Are the ecom-UNO and ecom-DP calibrated prior to shipment?
Yes—each unit ships with an ISO/IEC 17025-accredited calibration certificate (traceable to PTB standards), valid for 12 months under normal operating conditions.
Can the ecom-DP perform simultaneous dual-channel logging?
Yes—the instrument continuously acquires and time-synchronizes data from both pressure inputs at 1 Hz sampling rate, storing paired values with identical timestamps.
Is external power or charging required?
No—both models operate exclusively on standard alkaline AA cells; no rechargeable battery option or AC adapter is supported.
Does the ecom-DP Logger software support automated report generation?
Yes—it includes configurable report templates compliant with DIN EN 14597 and VDI 2047 guidelines, including pass/fail thresholds, annotated graphs, and digital signature fields.
What accessories are required for TRGI tightness testing?
A certified leak-test kit (including pressure regulator, shut-off valve, and calibrated test manifold) and the optional ecom-DP infrared printer for on-site thermal printouts of test certificates.
