Product Description

Structure of Flange type:

HGTF Target flow meter mainly consists of meter tube , stress element (target plate), sensing elements (force transducer, pressure transducer and temperature transducer), transition part (adjusted according to temperature and pressure), and accumulation calculation, display and output part. Refer to the following figure for the structure:

structure 1


The stress element (target plate) is placed at center of measurement tube (instrument body) coaxially, with rigid connection with transducers. When measured medium flows at certain velocity (m/s), this medium has certain momentum that directly acts on the stress element (target plate). Due to rigid connection between stress element and transducer, the transducer is subject to direct force F generated by fluid momentum. This force is related to flow velocity V, medium density ρ and area of target subject A , the relation meet the formula:  F = CD ρ V2 A / 2

F—force on target plate;   CD—resistance coefficient;   P—fluid density, kg/m3;  V—fluid velocity, m/s;    A—area of target plate subject to force, m2
the flow is calculated as follow fomular:

Its non-intrusive design minimizes pressure drop and reduces the risk of leaks, enhancing safety and system integrity. The flow meter is versatile and can be applied to a wide range of fluid types, from liquids to gases. It operates with minimal maintenance requirements and has a long service life, reducing operational costs. Additionally, it is suitable for both high and low flow rates, making it adaptable to various industrial and environmental applications. These advantages make the Target Flow Meter a valuable tool in industries such as oil and gas, chemical processing, and water treatment, where precise flow measurement is critical to performance and safety.

How to choose a suitable Target Flow Meter?
Choosing a suitable Target Flow Meter involves several key considerations. Firstly, determine the type of fluid you need to measure (liquid or gas) and its properties, including temperature, pressure, and viscosity. Next, establish the desired flow measurement range and accuracy requirements for your specific application. Consider the environmental conditions, such as hazardous or non-hazardous locations, and select a flow meter that meets safety and compliance standards.

What fluid types is Target Flow Meter suitable for?
The Target Flow Meter is a versatile instrument suitable for a wide range of fluid types, including both liquids and gases. It can be used in applications involving water, oils, chemicals, natural gas, steam, and various other fluids. Its adaptability to different fluid types makes it a valuable tool in numerous industries and applications where precise flow measurement is essential for optimizing processes and ensuring efficiency.

How to calculate the flow value based on the reading of Target Flow Meter?
Calculating the flow value based on the reading of a Target Flow Meter involves using a flow equation provided by the SUYI group. This equation relates the meter reading to the flow rate and typically includes factors like the meter’s constant, fluid properties, and specific design. After recording the meter reading, the equation is applied, considering parameters like temperature and pressure to determine the flow rate in appropriate units (e.g., GPM, L/s, CFM). Periodic calibration is essential to maintain measurement accuracy, ensuring that the calculated flow value aligns with the actual flow rate. Always refer to the SUYI group guidelines for precise calculations.

Can Target Flow Meter measure multiple fluids at the same time?
The Target Flow Meter is typically designed to measure the flow rate of one fluid at a time. It measures the flow of a specific fluid type based on its properties, such as density, viscosity, and temperature. While the Target Flow Meter is versatile and can be used for various fluids, it generally measures one fluid type in a specific flow stream. If there is a need to measure multiple fluids simultaneously, separate flow meters for each fluid type or a multiphase flow meter capable of handling mixed fluids may be required. Always consult with the SUYI group or a flow measurement specialist to determine the most suitable solution for your specific application.
