Product catalog summary

Overview
The AI.Gas.TF Series gas turbine flow meter is a precision instrument designed for measuring gas flow. It features low pressure loss, high accuracy, low initiating flow, and resistance to vibration and pulsation. It includes temperature and pressure sensors to ensure accurate measurements by converting working condition flow to standard condition flow. It is suitable for clean, low viscosity gases like air, natural gas, and methane, and is used in industries such as petroleum, chemical, and electric power.

Working Principle
The flow meter consists of a base table and display, with components like a rectifier, turbo, and sensors. Gas entering the meter is rectified and accelerated, causing the turbine blades to rotate. The rotation speed is proportional to the flow rate, and this is measured using electromagnetic induction. The signal is processed to display the standard instantaneous and total flow.

Features

Rectifying device for reliable measurement even with poor installation conditions.
Dust-proof structure to prevent impurities from causing wear.
Low installation requirements with specific pipe lengths for accuracy.
Intelligent design for dynamic temperature and pressure detection and compensation.
Durable aluminum alloy turbine with high accuracy and repeatability.
Advanced microcomputer technology for superior performance.
Low power consumption with options for battery or external power.
Large LCD display for easy reading in dark environments.
Various output options including pulse and 4-20mA signals.
RS485 communication for automated reading systems.
Data storage technology to retain settings after power outages.
Low voltage alarm for battery replacement reminders.
Rotatable integrating instrument for convenient reading.
Signal output calibration function and wide temperature LCD technology.
Isolation of external power from the main circuit for safety.
Reliable electromagnetic compatibility design.

Flow Range
The standard accuracy is 1.5%, with an optional 1.0%. The pressure loss is noted under standard conditions, and weight is referenced under 1.6Mpa. Custom pressure ranges or materials require verification.

Order Code
The order code for the AI.Gas.TF Series includes specifications for size, accuracy, body material, flow range, output/communication, power supply, flange standard, and ATEX version. Sizes range from DN25 to DN400, with various options for materials and outputs.

GAS TURBINE FLOW METER AI.Gas.TF Series

Open the catalog to page 1

AI.Gas.TF Series gas turbine flow meter is one kind of precision measuring instruments which for gas measuring. This flow meter has the characteristics of low pressure loss,high accuracy, low initiating flow, anti vibration and pulsation flow resistance, widely range ratio etc. When design AI.Gas.TF Series gas turbine flow meter, we consider the gas compressibility, Volume quantity is closely related with medium temperature and pressure, thus we add the temperature and pressure sensors so that monitor the change of medium temperature and pressure, directly make working condition flow change into...
