jual Electromagnetic flowmeter

HLN electromagnetic flow meter : Digital Flow Meter for condutive liquid case are made
from carbon steel, Electrode from titanium and linning from PTFE.
Novable parts in this meters, no loss pressure, simple structure,reliable. The accuracy
are not affected by the change of measured medium’s pressure density, temperature
viscosity & other, power comsumtion below 20 w.

APPLICATION
Widely applied in the fields of chemical, petroleum, metallurgy, food and beverange &
pharmaceutical industry water & waste water, agriculture & irrigation, paper marking.

Technical performance parameters
main power:AC220V 50Hz /DC24V/3.6V
Power consumption:<15W(Supporting power consumption with sensors)
Display and buttons:Display in Chinese and English, can display instantaneous flow, cumulative flow and alarm display (excitation open circuit alarm, empty pipe alarm, flow limit alarm). 4 membrane touch switches for data setting
counter:Forward total, reverse total
output signal
Analog output :Two-way two-way, fully isolated 0~10mA/4~20mA
Load resistance: 0 ~ 1.5kΩ when 0 ~ 10mA; 0 ~ 750Ω when 4 ~ 20mA
Frequency output:Forward and reverse flow output, the upper limit of output frequency can be set within 1 ~ 5000Hz. Open collector bidirectional output of transistor with photoelectric isolation. External power supply is not greater than 35V, the maximum current of the collector when conducting is 50mA
Alarm Output :Two open-collector alarm outputs with photoelectric isolation transistors. The external power supply is not greater than 35V, and the maximum current of the collector when it is turned on is 250mA. Alarm status: fluid empty pipe, excitation disconnection, flow overrun.
Pulse output :Forward and reverse flow output, the upper limit of output pulse can reach 5000CP / S. The pulse equivalent is 0.0001 ~ 1.0m³ / P. The pulse width is automatically set to 20ms or square wave. Open collector output of transistor with photoelectric isolation. External power supply is not greater than 35V, the maximum current of the collector when conducting is 50mA
Matching accuracy :± 0.5% of market value, optional ± 0.2% or 1% of indicated value
Damping time constant :Continuous variable from 0 ~ 100s (90%) time grading optional
communication :Optional RS232C or RS485 serial communication interface, HART communication protocol, with anti-lightning protection
Loss of power:The internal design of the instrument has a power-off clock, which can store 16 drop-out records (10 years)
Protection level:IP65
Explosion-proof mark:Exs[ia]ia||cT5

Lining material
 Polyurethane rubber:
1. Very good wear resistance coal slurry, mud, ore slurry, etc.

2. Not resistant to acid, alkaline and other corrosive or high temperature media

3. There must be no negative pressure in the pipeline
Neoprene:
1. Very good elasticity and wear resistance

2. Capable of measuring domestic sewage, non-corrosive industrial sewage PH value: in the range of 6/7/8, temperature below 80 ℃ liquid

3. There must be no negative pressure in the pipeline
Teflon F-4 PTFE
1. Boiling-resistant hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali and various organic solutions

2. Strong abrasion resistance and poor bonding performance

3. There must be no negative pressure in the pipeline
    Perchloroethylene propylene F-46(PTFE)
1. On the basis of all functions of PTFE, the temperature of non-corrosive liquid can be increased within 140 degrees
