XG-JF Series Metal Float Flow Meter

The XG-JF Series Metal Float Flow Meter is a variable area flow measurement instrument. It has the characteristics of small size, large detection range, and ease of use. It can be used to measure the flow rate of liquids, gases, and vapors, especially suitable for measuring the flow rate of low-velocity and low-flow media.      

Product Features:
1. Float flow meters have both on-site display and intelligent remote transmission types. The intelligent remote transmission type adopts high-performance computer chips, multiple signal outputs, and advanced data storage, with data recovery and backup to ensure data security.
2. According to the different measurement tube structures, the XG-JF series metal tube float flowmeter is divided into 50, 51, 52, and 53 types. Different measurement tube forms can be selected according to different user requirements, which further improves maintenance and cleaning.
3. The requirements for straight pipe sections are not high, with a wider flow ratio of 10:1 and a measurement range of 1-2000001/h for water (20 ° C); Empty (20 ° C, 0.1013MPa) 0.03-4000m3/h
4. Single-axis sensitive indication, non-contact magnetic coupling capability.
5. Optional options include a two-line system, battery, and AC power supply.
6. Suitable for high temperature, high pressure, and strongly corrosive media.
7. Multi-parameter calibration function; accuracy: 1.0% F.S., 1.5% F.S.       

Core selling points:
1. High temperature and high pressure resistance: The metal tube structure can withstand high medium temperatures and working pressures, adapt to harsh working conditions, and cannot be replaced by glass floats.
2. Strong adaptability: Capable of measuring gases and liquids, allowing the medium to contain a small amount of impurities, resistant to vibration, and suitable for harsh industrial environments on site.
3. Intuitive on-site display: No power supply is required to directly read the flow rate on site, and some models come with remote transmission output, balancing on-site viewing and remote signal acquisition.
4. Simple and reliable maintenance: simple structure, few moving parts, low failure rate, easy installation, and low maintenance cost in the later stage.

Application industry:
1. Petrochemical industry: Measure the flow monitoring of various process fluids, solvents, and gases.
2. Water treatment and environmental protection: Flow measurement of sewage, purified water, and chemical dosage.
3. Metallurgical steel: Flow detection of cooling water, process gas, and auxiliary media.
4. Energy and electricity: Measurement of flow rates for water vapor, compressed air, and various auxiliary media in power plants.

FAQ Performance Specifications

Q1: Can a metal float flowmeter measure media containing small amounts of impurities?
A: It can measure liquid and gas media containing small amounts of particulate impurities, but it is not suitable for high-viscosity, large-particle, and strongly scaling media; Excessive impurities can easily trap the float, causing inaccurate measurements. It is recommended to perform pre-filtration on the medium.

Q2: Does the metal float flowmeter require a power supply to display flow rate?
A: The basic on-site indicator does not require a power supply and can directly read the flow rate on site; Models with 4-20mA remote transmission and alarm output functions require an external power supply to output signals to the control system.

Q3: What are the mandatory requirements for installing a metal float flowmeter?
A: It must be installed vertically, and the medium flows through the instrument from bottom to top. To avoid strong vibration, keep appropriate straight pipe sections in front and behind, and do not use it horizontally or upside down; otherwise, it will directly affect the measurement accuracy.

Q4: How to choose between metal float flowmeter and glass tube float flowmeter?
A: Metal floats are preferred for high temperature, high pressure, and vibration conditions; Glass tubes have low cost and good visibility, but have limited pressure and temperature resistance, are fragile, and are not suitable for flammable, explosive, high-pressure,e and harsh working conditions.
