HDS-ENY intelligent online level gauge consists of a primary instrument of detection of material level; signal sample device of liquid flow and voltage change; signal sample device of fluid temperature; and the secondary meter of signal treatment of level gauge.
1. For the online detection of the flow level changes, in order to better improve the precision, it adds the signal check of liquid flow and pressure change.
2. It can spontaneously show the material level value and percentage, and have the analog output of the two parameters, alarm output of the relay bound.
3. There is no process interrupt for continuous online detection of liquid level that can be directly used in the production process control; it can be used for fluid or static liquids that is suitable for installation of pipes and tanks.
4. The parts in touch with the liquids are all made of stainless steel, safety and sanitation.
5. Intrinsic safety type can be used in dangerous environments; sanitary type can be installed in the site of food production.
1.The range of measurement:0-10m,if using multithreading, the equipment could measure the change of the material level at the range of tens meters.
2. The way of the signal: 0-5V/0 – 10kHz, with analog output and switch output.
3. The measuring precision of material level: +0.5% ~ +1% full scale.
4. Instruction signal processing ways: The equipment use the multipoint signal to calculate the calibration. (The general is flexible chose at the range of 2 ~ 15 points, and the most is up to 15 points calibration).
5. The time constant: 0 ~ 10s (fast), 10 – 100s (slow).
6. Environment temperature: The temperature of the host is -10~45℃，the temperature of the probe is -20 ~ +65℃.
7. Environment humidity: The humidity of the host is 85%.
8. The output signal: It use two road 12 full isolation analog output, it has two roads material level value and the percentage level 4-20mA instantaneous material level signal, 4-20mAPID control output, it also support RS485 communications output.
9. Upper limit and lower limit alarm: We can set it by keyboard. The equipment can provide the relay contact output.
10. The size of the host appearance: 143x73x310mm, the size of the host holes is 138x68mm.
11. The instantaneous filtering constant is 0 – 99.
12. The signal transmission distance: standard distance is 800m (The longest is up to 3000m)
The display mode: With removing large LCD dot matrix display screen.
The type of installation: Secondary instrument, plate mounted, wall hanging.
The sugar industry and the wine-making industry use it to extract juice, syrup, alcohol, etc.
The dairy industry can use it to condensed milk, lactose, cheese, cream cheese, lactic acid, etc.
Mining coal, potash, salt, phosphate, calcium compounds, limestone, etc.
Refining lubricating oil, aromatic, fuel, vegetable oil, etc
Tomato juice of food processing industry, grape juice, lemon juice, marmalade, etc
The pulp and paper industry black slurry, green pulp, pulp washing, white pulp, caustic, etc
Beverage industry beer, soft drinks, fruit wine, instant coffee, etc.
The field of Chemical industry acid, caustic soda, urea, sodium chloride, sodium hydroxide, etc.
The natural gas of Petrochemical industry, kerosene, lubricants, oil/water interface, etc.
