Heinrichs TSK-S375BN2U5V0-0-S51-0-H 16″ Paddle Flow Meter

Heinrichs TSK-S375BN2U5V0-0-S51-0-H Paddle Type Flow Meter 16″ – NEW

The Heinrichs TSK-S375BN2U5V0-0-S51-0-H is a 16-inch paddle/flap-type flow meter engineered for precise continuous measurement and monitoring of liquid and gas media within large-diameter piping systems. Built upon Heinrichs Messtechnik’s robust TSK platform, this unit utilizes an encapsulated ring-type permanent magnet system coupled with an internal pivoting paddle (flap) mechanism that deflects proportionally to the flow velocity.

As a veteran marine engineer, I can attest that large-diameter fluid lines aboard commercial vessels, FPSOs, and processing plants demand instrumentation capable of withstanding hydraulic shock, continuous vibration, and aggressive fluid dynamics. This specific model features high-integrity material construction and dual limit switch integration, making it an ideal drop-in replacement or primary installation for critical high-capacity fluid handling networks where standard differential pressure or rotameters fail due to scale or particulate loading.

Technical Details

Key Features

1. Robust Mechanical Design: All-metal wetted components designed to handle high flow velocity spikes and continuous operating stresses without mechanical deformation.
2. Magnetic Coupling Transmission: Hermetically isolates the fluid chamber from the indicator/switch compartment, preventing leakage risks in hazardous environments.
3. Integrated Limit Switches: Equipped with factory-fitted switch configurations (-S51-) for reliable automated safety interlocks and threshold triggering.
4. Large Diameter Capability: Precision-engineered for 16-inch piping infrastructures, reducing pressure drops compared to restrictive constriction meters.
5. Maintenance-Friendly Architecture: Simple internal flap mechanism allows for straightforward inspection and servicing when system drains permit.

Applications

• Marine Engineering: Main cooling water lines, ballast water management systems, and centralized bilge/fire main monitoring.
• Petrochemical Processing: Hydrocarbon transfer loops, heavy chemical feed lines, and cooling tower circulation circuits.
• Water & Wastewater Treatment: High-capacity effluent discharge manifolds and raw water intake main lines.
• Power Generation: Auxiliary sea water service pumps, condenser cooling circuits, and large-scale thermal plant fluid distribution.

Compatibility & Equipment Models

• Compatible Pipe Standards: ANSI B16.5 / DIN EN 1092-1 16-inch industrial flanges.
• Interfacing Control Systems: Compatible with standard PLC analog/digital input cards, DCS systems, and standalone alarm annunciator panels accepting dry contact inputs.
• Interchangeable Series: Direct configuration replacement for legacy Heinrichs TSK series meters of identical nominal bore size.

Frequently Asked Questions

What type of media can the Heinrichs TSK-S375BN2U5V0-0-S51-0-H measure?

This meter is designed for both liquid and gas applications compatible with stainless steel wetted parts. It excels in high-viscosity or particle-laden industrial fluids where traditional turbine or magnetic meters might experience fouling or high pressure drops.

How are the limit switches wired on this model?

The unit utilizes integrated terminal blocks housed within the weather-resistant terminal enclosure. The switches provide potential-free changeover contacts that can be integrated directly into safety instrumented systems or local alarm panels.

Can this 16-inch flow meter be installed in a vertical pipe run?

Yes, provided the flow is moving in the correct directional arrow stamped on the meter body. Vertical installation requires careful consideration of gravity effects on the counterbalanced paddle assembly during calibration.
