Description
■ Features
1. Adjustment and control of the flow are possible with the digital screen.
2. Digital air flows for integrated PF2A series and separate types of monitor are available.
3. Three types of output: switch, accumulated pulse and analog outputs.
4. capable of alternating between accumulated and instant flow.
5. 4 channel flow monitor: 4 independent flow ranges can be monitored by a single controller.
■ How to order PF2A Air Digital Flowers Series
■ Specs
*1) Digital flow switch with units switching function. (The unit if it sets [(l/min, or l, m³ or m³ × 10³)] will be established for the type of switch without the commutation function of units).
*2) Flow screen can be changed between the basic condition of 0 ℃, 101.3 kPa and the standard condition (ANR) of 20 ℃, 101.3 kPa, and 65% HR.
*3) The tubes on the inlet side must have a straight section of the pipe whose length is 8 times the diameter of the pipe or more. If a straight pipe section is not installed, the precision can vary in ± 5% F.S. or more.
*4) Accumulated capacity is restarted when the power supply is turned off.
*5) Switching and exit of selectable accumulated impulses during the initial adjustment.
*6) Window comparator - since hysteresis will reach 3 digits, keep P_1 and P_2 or N_1 and N_2 separated by 7 digits or more. (In the case of out2, N_1, 2 must be N_3, 4 and P_1, 2 must be P_3, 4.)
*7) Digital air flows for more details on wiring and thread type, contact VPC.
*8) Any product with small scratches, spots or variations in the color or brightness of the screen that do not affect performance is verified as a compliant product.
■ analog output
* When you use the analog output of the standard state, conversion according to the following formula.
Value of the base state flow ÷ 0.927 = value of the standard state flow.
