Tri Gear Chemical Flow Meter

Introduction

Performance accuracy along with shelf life are on stake when it comes to operate for Acid and other strong chemicals that easily harm the equipment used. The Trigear chemical flow meters have been designed with highly durable alloys and PVDF body, supporting the flow-less and effort free operations and fluid measurement. The PEEK material gear supports sturdy operation and enhance the shelf life.

FAQ's

A Tri Gear Chemical Flow Meter is a positive displacement flow meter designed to measure the flow of viscous chemicals and corrosive fluids. It uses 2 interlocking gears that rotate as the fluid passes through, displacing a fixed amount of fluid with each rotation. The rotation is measured and converted into flow rate, providing accurate and repeatable readings even with high-viscosity media.

Tri Gear Chemical Flow Meters are typically made from chemically resistant materials like PVDF, PEEK and Hastelloy C. Seals and gears may use materials like Viton and PTFE, depending on the fluid's chemical compatibility.

They can handle mildly abrasive fluids, but excessive abrasives may cause wear on gears and internal parts. For such applications, special materials or coatings may be required. Regular maintenance and monitoring are also advised.

Yes, Tri Gear Flow Meters are suitable for both continuous flow monitoring and batch control applications. They can be integrated with automation systems to control filling, dosing, and dispensing based on precise flow measurements.

These meters require minimal maintenance due to their robust design. Periodic inspection for wear on gears and seals is recommended, especially when handling abrasive or aggressive fluids. Proper flushing after use with harsh chemicals can help extend the meter's lifespan.
