Flow

Overview

Gas Roots flowmeter is a kind of gas monitoring and measuring instrument with high precision, high reliability and wide range.

Intelligent gas Roots flowmeter is a new type of flowmeter which integrates flow, temperature, pressure sensors and intelligent integrator. It widely application for measuring non-corrosive gases such as natural gas, city gas, propane, nitrogen, industrial inert gas, etc.

Features

• Wide range: the highest range reaches 1: 216
• Low initial flow: the Min. starting flow reaches 0.04m3/h.
• High precision and repeatability
• Low pressure loss: 0.08kPa-0.58kPa.
• High integration and low power consumption
• Compact structure: built in pressure sensor, temperature sensor and flow sensor
• Digital pressure temperature sensor
• Segment correction
