1. Initial password for Fuma flowmeter
Currently, there is no clear public information indicating the initial password for Fuma flowmeter. Due to the significant differences in password system design among different brands of flow meters, it is recommended to refer to the known brand password structure and combine the following clues for comprehensive processing.
1. The conventional solution is to first consult the product manual or directly contact the manufacturers customer service to obtain accurate information.
. The password for a flow meter is usually associated with the device model, permission level, or production batch, and non universal passwords are difficult to query through public channels. 2. Other brand password structures refer to the following: • Hierarchical permission system: • L-magF electromagnetic flow scoring five level password (such as level 1 00522, level 4 07206) • User password for a certain instrument with a dust core score of 0-3 levels (such as a fixed value of 0521 for level 0 and a factory value of 7206 for level 1) • Factory default password: • HFD3000, Dongde Excavator DPT100 type, etc. use 0000 • Cologne ultrasonic flow meter engineer password is 7378, and radar vortex flow meter uses 0058 • Password triggering method: The flow meter of Leonic Brother Qing needs to be operated through a combination of keys, enter the password 321 3 If the factory password cannot be obtained, the following combinations or methods can be tried: • Common 4-digit default passwords such as 0000, 1234 • 6-digit passwords may involve the year of manufacture or model code (e.g. 00052
1, 071049) • When attempting to reset parameters, be aware that advanced access passwords may n

2. What is the unit of a float flowmeter?
The unit of a float flowmeter is L/h or m ³/h. Other symbol units: Q - maximum flow rate of the measured liquid, L/h； ρ f - Float density, g/cm3， For a hollow float, ρ f=Gf/V, where Gf is the mass of the float (g) and V is the volume of the float, cm3； ρ. ρ water - the density of the measured liquid and water, g/cm3。 Additional information: Characteristics of nuclear liquid float flowmeter Float flowmeter is used for small diameters and low flow rates. Commonly used instruments have a diameter of 40-50mm or less, with a minimum diameter of 1.5-4mm. They are suitable for measuring low flow rates and small flow rates. Taking liquids as an example, the nominal diameter of a glass tube float flowmeter with a diameter of 10mm or less for full flow rates is only between 0.2-0.6m/s, or even below 0.1m/s; The metal tube float flowmeter and glass slide tube float flowmeter with a diameter greater than 15mm are slightly higher, with a flow rate between 0.5-1.5m/s. Float flow meters can be used for lower Reynolds numbers, using floats with viscosity insensitive shapes. As long as the Reynolds number at the flow annulus is greater than 40 or 500, the flow coefficient remains constant when the Reynolds number changes, meaning that changes in fluid viscosity do not affect the flow coefficient. This value is far below the minimum Reynolds number requirement of 104-105 for standard orifice plate and other throttling differential pressure instruments. Most float flowmeters do not require an upstream straight pipe section, or in other words, do not have high requirements for the upstream straight pipe section. Float flow meters have a wid
