QUANTOMETER QA / QAE Meter: High-Performance Turbine Flow Meters for Industrial Applications

The QUANTOMETER QA / QAE Meter is a reliable and efficient turbine flow meter designed for non-fiscal applications in industrial and commercial environments. Available with either a mechanical totalizer (QA) or an electronic totalizer (QAe), this meter ensures precise measurement of gas flow rates and consumption. Its robust design, high accuracy, and maintenance-free operation make it an ideal solution for industries focused on energy efficiency and consumption monitoring.

Product Overview

• Product Name: QUANTOMETER QA / QAE Meter
• Medium: Natural gas, air, methane, nitrogen, and other non-corrosive gases
• Applications: Boilers, heaters, furnaces, in-plant allocation metering, volume input for controls, and consumption monitoring
• Industries: Heavy and light industry, petrochemicals, steel, power, minerals, and heating

Operating Principles

The QUANTOMETER operates on the turbine principle, where the gas flow sets a turbine wheel in motion. The revolutions of the wheel are directly proportional to the gas volume passing through the meter. The measured volume is recorded via a mechanical totalizer (QA) or an electronic totalizer (QAe). Self-lubricating bearings ensure long-lasting, maintenance-free performance.

Energy Efficiency and Cost Allocation

• Quantometers help industries optimize energy usage by providing detailed consumption data for improved process control and energy savings.
• Internal cost allocation between departments becomes streamlined with precise metering data.

Installation Requirements

• Piping Requirements: 3DN of straight upstream piping and 2DN outlet in the same nominal size as the meter for accurate measurements.
• Filter Recommendation: A filter must be installed upstream to protect the meter from particulates like rust.
• Installation Orientation: Compatible with horizontal or vertical installation; flow direction defined at the time of order.

Applications

• Energy Efficiency Monitoring: Boilers, heaters, and furnaces in industrial plants.
• Cost Allocation: Accurate metering data helps allocate gas consumption costs between departments or cost centers.
• Volume Input Control: Ideal for industrial burners and control systems in petrochemical, steel, and heating sectors.
