I think that I need to connect pulse output from controller to HSC? Every suggestion is welcome. Thank's Attachment DS8035-Batch-EU-EN.pdf (802 Downloads)

0_Einstein Diamond Member Joined: 7/7/2010 Last visit: 9/5/2025 Posts: 16061 Rating: (2513)	Milosh Datasheet Fig 21 of the 2nd posted datasheet shows how to wire it up to the plc. Yes, you would connect to a HSC input so you could convert the pulses to frequency and calibrate as required for your project. If you have the PNP or NPN style batch controller, you wire per that Figure. Hopefully it is pnp to make things easier for you.

Milosh Silver Member Joined: 8/16/2010 Last visit: 6/18/2025 Posts: 640 Rating: (12)	Thank's. But I'm little bit confused. On Fig 21. on PLC side I have + and - 5-36VDC? I need to connect P+ output of the device to HSC input of PLC, and P- from 0V of my power supply. (see attached doc.) Specification: frequency is from 0.6 to 2200Hz, HSC is 100Hz. Is that essential for accuracy of flow? How to handle that on TIA side? Attachment pulse.pdf (862 Downloads)

Milosh Silver Member Joined: 8/16/2010 Last visit: 6/18/2025 Posts: 640 Rating: (12)	Hello to all. I finally got the flowmeter. It is burkert 8030 (electronic SE30 an fitting S030) with PNP pulse output. DN20 with paddle wheel. K factor for the that is 66,5 pulses/litre. I need to know how to configure HSC in TIA (type of counting, operating phase and other). For now I configure type as counting, and operating phase as single. Counting works. I think that I need to multiply every pulse with some number to get amount of litres?

I need to know how to configure HSC in TIA (type of counting, operating phase and other). For now I configure type as counting, and operating phase as single. Counting works. I think that I need to multiply every pulse with some number to get amount of litres? I recently posted (today) about a similar setup. I suggested setting the HSC configuration to frequency. Then your flow rate, Q, is directly proportional to frequency, f, by the K factor, 66,5 ppl. If your HSC input is ID1000 is the frequency measurement, you will want to tune your digital input filtering to match your needs as well - which you may have done already for the HSC to work. To get your Q, simple algebra: Q = f / k = ID1000 x 66,5 x time-scale-factor-as-required Please post back what you find.

Time scalefactor changes it from litres/sec to whatever unit you need. Do the math to obtain your time-scale-factor and put it there.

Sorry, but maybe I didn't understand... Ok, I think I understand what you mean. You need to know how much of something has flowed, not how fast it is flowing. In that case, you would use your HSC as a counter, and when you start your batch, you set the count to 0, and count up until you have reached the required amount of stuff. The problem then relates to the K factor to know there are "k" pulses per litre. So start counting until it reaches the right number of pulses. Your recipe will define how many litres, right?

Milosh Silver Member Joined: 8/16/2010 Last visit: 6/18/2025 Posts: 640 Rating: (12)	Yes, that's it. I think like this: 1. K factor is 66,5 pulses per liter 2. So one pulse is about 0,015 litres (1/66.5) 3. operator set litres on touch panel ( example 10 litres) 4. when convert that, it's 665 pulses (10l * 66,5 p/l) 5. when counting one pulse is about 0.015, so when multipling pulse*0.015 I get the amount of flow in litres Right?

So if you have little time to give some example for math you provide in earlier post: Q = f / k = ID1000 x 66,5 x time-scale-factor-as-required let say that I need Q in m/s???

So if you have little time to give some example for math you provide in earlier post: Q = f / k = ID1000 x 66,5 x time-scale-factor-as-required let say that I need Q in m/s??? If you can convert your fluid flow rate from litre/sec to meter/sec, then yes, I can explain. You need to know how many meters equate to a litre, which will involve the pipe diameter and volume per meter. If you are looking for details on this, your favorite fluid dynamics wiki site can provide much more in the way of details, formulae, and explanation. f = pulses / sec (or 1/sec) k = pulses / litre f / k = (pps / ppl) = l/s (unit analysis) Q = flow rate = l/s Your controller documentation maystate f = Q x k, and I just turned it around for you.

Milosh Silver Member Joined: 8/16/2010 Last visit: 6/18/2025 Posts: 640 Rating: (12)	Yes you are right. f=kxQ => Q=f/k => frequency (ID1000) [p/s] / 66,5 [p/l] So i get flow rate in litres per second?

Correct. If you need it in other unit(s), just scale either for litres or seconds to whatever unit you need. If you end up trying to do mass flow rate, you will have to enter the density in your recipe. If the density changes with time, well, now you have a problem estimatingmass, and your controller may not be the right solution.
