GreenPrima PS TAB500 Electromagnetic Flow Meter – Inline Installation Type

Overview

The GreenPrima PS TAB500 is a high-performance inline electromagnetic flow meter engineered for continuous, contactless volumetric flow measurement of conductive liquids in industrial process control environments. Based on Faraday’s Law of Electromagnetic Induction, the device generates a magnetic field perpendicular to the direction of fluid flow; as the conductive medium passes through this field, it induces a voltage proportional to the average flow velocity. This principle ensures measurement independence from fluid density, viscosity, temperature, pressure, and moderate variations in conductivity—provided the liquid maintains a minimum electrical conductivity of 5 µS/cm. Designed for permanent pipeline integration, the PS TAB500 supports nominal pipe sizes from DN10 to DN2200 and operates reliably across fluid velocities ranging from 0.1 to 15 m/s. Its robust construction, absence of moving parts in the measuring tube, and low straight-pipe requirement (typically 5D upstream / 2D downstream) make it especially suitable for retrofit installations and space-constrained facilities.

Key Features

• Full-bore, obstruction-free measuring tube with zero pressure loss and minimal installation footprint
• Bi-directional flow measurement capability with real-time direction indication and separate forward/reverse totalization
• Integrated self-diagnostics including electrode contamination detection, empty-pipe recognition, and coil integrity verification
• Wide operating temperature range: fluid –30 °C to +250 °C; ambient –30 °C to +65 °C
• Multiple electrode material options (316L stainless steel, Hastelloy B/C, titanium, tantalum, platinum-iridium, niobium) for corrosion resistance in aggressive media
• Flexible liner selection—including PTFE, F46, chloroprene rubber, and polyurethane—to match chemical compatibility requirements
• IP65/IP67/IP68 enclosure ratings available, supporting outdoor, washdown, and submersible applications
• High-accuracy performance: ≤ ±0.3% of reading (typical), repeatability ±0.1% of reading

Sample Compatibility & Compliance

The PS TAB500 is validated for use with a broad spectrum of conductive process fluids, including strong acids (e.g., H₂SO₄, HCl), caustic solutions (e.g., NaOH), slurries (mining tailings, fly ash), pulp suspensions, wastewater, and food-grade liquids. It complies with international electromagnetic compatibility standards (IEC 61326-1), safety requirements (IEC 61010-1), and pressure equipment directives where applicable. For regulated industries, the device supports audit-ready operation via optional firmware enabling electronic signature, user access levels, and tamper-evident event logging aligned with FDA 21 CFR Part 11 and GMP/GLP documentation practices.

Software & Data Management

The flow meter provides configurable analog and digital outputs: standard 4–20 mA current loop (HART-enabled), pulse/frequency output, and dry-contact relay signals. Digital communication interfaces include RS485 (Modbus RTU, default), RS232, and optional HART or GPRS modules for remote telemetry. Configuration and real-time monitoring are performed via the built-in backlit LCD with intuitive multilingual menu navigation (English interface standard). Optional PC-based configuration software enables advanced setup, data export (CSV), and firmware updates. All operational events—including flow alarms, sensor faults, and power interruptions—are timestamped and stored in non-volatile memory for traceability.

Applications

• Chemical and petrochemical processing: dosing control, reactor feed, effluent monitoring
• Water and wastewater treatment: influent/effluent metering, sludge flow, chemical dosing verification
• Mining and mineral processing: abrasive slurry transport, leachate flow, tailings management
• Pulp and paper industry: white water recirculation, coating solution delivery, black liquor measurement
• Pharmaceutical and biotech manufacturing: CIP/SIP line validation, purified water distribution, buffer preparation
• Food & beverage production: syrup blending, CIP return flow, beer/wine transfer metering

FAQ

What is the minimum conductivity required for accurate measurement?
A minimum liquid conductivity of 5 µS/cm is required to ensure stable signal generation and noise immunity.
Can the PS TAB500 be installed in vertical pipelines?
Yes—vertical mounting is supported for both upward and downward flow, provided full pipe fill is maintained and grounding rings or electrodes are properly configured.
Is battery-powered operation available?
Standard models operate on 85–260 VAC or 11–40 VDC; an optional internal lithium battery pack (3.6 V, >5 years life) is available for remote or hazardous-area installations.
How does the device handle air or gas entrainment?
The integrated empty-pipe detection algorithm identifies partial filling or gas pockets and triggers configurable alarms while maintaining measurement continuity where possible.
Does the PS TAB500 support SIL certification?
The core electronics architecture meets IEC 61508 functional safety requirements up to SIL2 when deployed with certified redundant systems and appropriate system-level validation.
