SB-2100 flow integrator

summary:

The SB-2100 series integrator adopts a 12864 graphic dot matrix LCD display, which can measure the mass flow rate, heat flow rate, thermal difference, standard volume flow rate, etc. of the medium through a fully Chinese menu setting. It consists of five models: 2100A, 2100D, 2100H, 2100V, and 2100W. Among them, 2100A is a universal model suitable for measuring the flow rate, heat, etc. of saturated steam, superheated steam, hot water, and general gases; 2100D adds protocol metering function on the basis of 2100A, which can perform protocol metering on traffic exceeding the set range; 2100H is used for measuring the inlet and outlet heat difference of saturated steam, hot water, or hot oil according to the national urban construction industry standard CJ 128-2000; 2100V is a matching accumulator used for V-shaped cone flow meters; 2100W is a matching accumulator used for bend tube flow meters.

Main performance indicators:

1. Traffic input signal:

Receive 0-10mA and 4-20mA current signals from differential pressure transmitters and electromagnetic flow meters, or 0-5000Hz frequency signals from vortex flow meters.

Note: ① Standard for frequency signal: V low ≤ 1V, V high ≥ 5V

② Range of receiving frequency: 0-5000Hz HH

2. Pressure input signal (compensation signal):

Receive current signals of 0~10 mA or 4~20mA from pressure transmitters.

3. Temperature input signal (compensation signal):

It can receive current signals from temperature transmitters ranging from 0~10 mA or 4~20mA, as well as resistance signals from Pt100 platinum resistors.

4. Output signal (to be equipped according to user ordering requirements):

According to the changes in instantaneous flow rate and the set upper and lower limits of flow rate, output a current of 4~20mA. The output current of SB-2100H is proportional to the instantaneous thermal difference.

5. Measurement accuracy:Accuracy level 0.5

6. Communication function (to be equipped according to user ordering requirements):

Equipped with RS485 or RS232 communication interface and lightning protection.

7. It has multiple flow meter modes that can be freely selected.

8. The density of steam is calculated using the "IFC-1967 Formula Part I Zone II"Automatically identify the superheated and saturated state of steam, using temperature and pressure compensation,Measure mass flow rate.Having the density of hot water and hot oil; The enthalpy of steam, hot water, and hot oil.

9. Display function:

a. SB-2100A, D, V, W: Accumulated flow rate, instantaneous flow rate, accumulated heat, instantaneous heat, differential pressure (frequency), density, pressure, temperature, enthalpy, current time, and incoming power outage records.

b. SB-2100H: Cumulative flow rate, instantaneous flow rate, cumulative heat (difference), instantaneous heat (difference), differential pressure, frequency, density, pressure, inlet temperature, outlet temperature, current time.

10. Report query function:

You can query the daily and monthly cumulative volume reports for the past year, as well as the last 20 power outage records, cumulative outage time, and cumulative outage frequency.

11. Forced restoration accuracy function:

Unplug the power ->press and hold the "confirm" button ->turn on the power and you will hear a "beep" sound ->the instrument returns to the measurement accuracy at the factory.

12. Protocol measurement (unique to SB-2100D):

① Protocol lower limit: Any flowmeter has a minimum flow rate that guarantees accuracy. If the flow rate further decreases, sensitivity loss (such as vortex flowmeter) or being cut off as a small signal will occur, which is unfavorable for the supplier. Therefore, to prevent the loss of benefits, the supply and demand parties can agree on a certain flow rate as the "flow lower limit". When the actual flow rate is less than the agreed value, the measurement will be based on the agreed value (note: when the flow rate stops or the flow signal is less than the set small signal cut-off value, this instrument still measures zero).

② Protocol upper limit: In order to encourage users to plan their energy consumption and operate within the set range, the supply and demand parties can agree on a certain flow as the "flow upper limit" and agree on the "protocol coefficient". When the actual flow exceeds the agreed "flow upper limit", the excess will be measured by multiplying the value by the protocol coefficient. For example, if the agreed "flow limit" is 100 tons/hour and the "agreement coefficient" is 2, when the actual flow rate is 150 tons/hour, this instrument will display 200 tons/hour (100+(150-100) × 2)

13. Power off protection function:

The calculation results inside the machine and the data set by the user will not be lost during power outage, and will be saved for more than ten years.

14. Automatic judgment function for the conversion of superheated steam to saturated steam:

15. Working power supply:

AC：220V±15%; Power consumption: less than 5W

16. Output power supply:

There are 2 groups in total, one group is 12V/1W, and the other group is 24V/2W; Two sets of power supplies are not grounded together.

17. External power supply function (to be equipped according to user ordering requirements):

This instrument can accept dual power supply from AC and DC power sources. When the AC power supply is cut off, it automatically activates DC 12V as the power supply for the instrument. When the AC power supply is restored, it automatically switches back to the AC power supply.

18. Work environment:Temperature: 5-50 ℃; Humidity: 5-95% RH
