Introduction

Q&T Liquid Turbine Flow Meter is internally developed and perfected by Q&T Instrument. Over the years, Q&T Liquid Turbine Flow Meter has been commissioned in many parts of the world, received praise from end-users and industrial leaders.
Q&T Instrument Turbine Flow Meter offers two accuracy classes, 0.5%R and 0.2%R. Its simple structure allows a small pressure loss and virtually no maintenance requirements.
The Thread Connection Turbine Flow Meter offers two types of converter options, Compact Type (Direct Mount) and Remote Type. Our users can select the preferred converter type depending on the commissioning environment. Q&T Thread Connection Turbine flow meter is the most popular turbine product used in systems with small pipe sizes.

Advantages

Thread Turbine Flow Meter Advantages
Q&T strives to provide high-quality products with economical cost.
Q&T Liquid Turbine Flow Meter applies to viscous fluids, non-conductive fluids, solvents, liquefied gases and high-pressure applications.
Q&T Instrument Liquid Turbine Meter provides high accuracy of 0.2% R and a wide range of applications to non-conductive liquids, such as fuel oil, ultrapure water and gasoline. These make the turbine meter more popular compare to Electromagnetic Flow Meter in the oil industry, purifying process and distilleries. The Q&T Instrument meter also has an amazingly wide turndown ratio of 20:1, combined with its mechanical designings enables the meter to operate reliably in both high and low flow rates and produce excellent repeatability as low as 0.05%.
The Thread connection Turbine Flow Meter is known for its application to smaller pipe sizes. In the case of limited installation space, Thread connection Turbine Flow Meter is always preferred over Flanged connection and Tri-Clamp connection Turbine Meters.

Application

Thread Turbine Flow Meter Applications
Q&T Instrument Liquid Turbine Meters offers both standard SS304 body and SS316 body. Because of its wide working temperature and pressure range, it is capable of measuring various mediums and commissioning into extreme working conditions.
Q&T Instrument Liquid Turbine Meters are popular in the Oil & Gas industry, Chemical industry, and Water industry. The Thread connection version is designed exclusively for smaller size pipes. Our standard size range for Thread Connection Turbine meter is from DN4~DN100.
Due to its high accuracy and fast response time, Q&T Instrument Liquid Turbine is often integrated into the Industrial Internet of Things, together with valves and pumps to achieve smart process control, for example, solvents batching, blending, storage and off-loading systems. Kindly contact our sales engineers if there are questions related to integrating Q&T Liquid Turbine Meters into your existing plant IOT.

Installation

Q&T Thread turbine flow meter installation
Before the installation, it is crucial to communicate with our sales engineers regarding the working conditions and medium the meter designs to measure.
The installation of the Q&T Thread Connection Liquid Turbine Meter involves minimal assistance. The users will not need additional tools for Thread type Turbine Flow Meter.
The user needs to keep in mind these three factors while carrying out the installation.
1. There should be at least ten pipe diameter lengths of straight pipe upstream of the Turbine Meter and five pipe diameter length of straight pipe length downstream of the Turbine Meter, with the same nominal diameter size.
2. Valves and Throttling devices needed to install downstream of the flow meter.
3. The arrow indicated on the meter body is the same as the actual flow.
If there are specific questions regarding the installation of the Q&T Instrument Turbine Meter, kindly contact our sales engineers for assistance.
