FLOWMETER HTF Target Flow Meter

Product catalog summary

Overview
The HTF Target Flow Meter is an advanced intelligent flowmeter that combines traditional measurement principles with modern sensor and digital technology. It is designed for high accuracy and reliability without moving parts, making it suitable for various industries such as petroleum, chemical, energy, food, environmental protection, and water conservancy.

Features

Capable of measuring liquids, gases, steam, and viscous mediums across a wide temperature range.
High sensitivity for ultra-small flow measurements, with a minimum flow velocity of 0.8m/s.
High precision with a total measurement accuracy of 0.2%.
Wide measuring range with a maximum ratio of 1:30.
Good repeatability between 0.05% and 0.08%.
Low pressure loss, approximately half that of a standard orifice plate.
Strong anti-interference and anti-impurity capabilities.
Dry calibration method available.
Easy installation and maintenance.

Structure & Principle
The flowmeter consists of a measuring tube, force element, sensing elements (force, pressure, temperature sensors), and an integrated display and output part. The flow measurement is based on the force generated by the medium's kinetic energy and pressure difference, proportional to the square of the flow rate.

Structure & Principle 1. Structure The intelligent target flowmeter is mainly composed of measuring tube (shell), force element, sensing element (force sensor, pressure sensor, temperature sensor), transition part (increased or decreased according to temperature and pressure), integrated display and output part, Its structure is as the figure shown: 2. Principle When the medium is flowing in the measuring tube, due to its own kinetic energy and the pressure difference generated by the choke, force of a pair of force elements are generated. The force is proportional to the square of the medium...
