Full Custody Transfer Approval: While standard meters are for "reference only," the E Heat carries the MID certification required by law for fiscal billing and carbon tax reporting.
Optimized for Insulated Pipes: The sensor design allows for clean installation within pipe insulation, preventing thermal bridges and maintaining your facility's energy efficiency.
Anti-Tamper Security: Once installed, the metrological settings and pulse outputs are locked, preventing any unauthorized tampering or accidental changes to billing data.
Maintenance-Free Ultrasonic Principle: No moving parts means no mechanical wear over time. Unlike turbine meters, the E Heat maintains its Class II accuracy for years without recalibration.
Plug & Play Deployment: Pre-configured and factory-calibrated, the E Heat requires zero commissioning. Simply install, power up, and start collecting verified data.
The Challenge: A large-scale manufacturing park needed to accurately bill multiple sub-tenants for heat consumption. To meet legal transparency requirements and settle potential disputes, the flow sensors had to be MID-certified and robust enough to handle 140 °C pressurized hot water.
The Hanyu Solution: The park standardized on the Prosonic Flow E Heat from
The Result: The Accuracy Class II rating provided the verified legal basis for all energy invoices.
The Impact: The park achieved a 100% compliant energy management system. The status LEDs allowed the maintenance team to verify thousands of meters at a glance, reducing diagnostic time by 80% and eliminating energy billing disputes between tenants.
Q1: What is the benefit of a MID-certified meter like the E Heat?
A: MID (Measuring Instruments Directive) certification ensures the meter has undergone rigorous third-party testing for accuracy and reliability. It is legally required for any application where energy is being sold or billed to a third party.
Q2: Can it be used for both heating and cooling water?
A: Yes. The Prosonic Flow E Heat is a dual-purpose sensor designed to handle the thermal ranges of both industrial heating systems (up to 150°C) and chilled water cooling loops.
Q3: How does the "Locked Output" work?
A: To comply with fiscal regulations, the pulse output used for billing is hardware or software locked at the factory. This ensures that the K-factor cannot be altered on-site, protecting the integrity of the fiscal record.
Q4: How does Hanyu Zhilian support my energy project?
A: We provide comprehensive technical consulting to ensure your energy management system meets all local and international standards. Per our Privacy Policy, all project data shared via
💡 System Integration Tip:
For maximum custody transfer precision and MID/OIML compliance, the FLOWSIC series is ideally paired with the [SICK Flow-X High-Precision Flow Computer].
