IoT remotely solution in flowmeter after sale service

Customer relationship is important! Comate IoT remotely solution in flowmeter after sale service help to tighten your bond with your customers!

When a complaint from customers, normally you ‘re facing four part problems:

  • Endless site travel. You need to assign your engineer to help on the site. Painful is when the address is very far away from your position.
  • Complicated setting check. You don’t know where the problems come from, if you’re new to this device you need to go though the manual over and over and contact the supplier and check again the settings.
  • Shipping here and back case time&cost waste. Normally they just send you a new meter for replace for most of the suppliers, that is good. But sadly, problems still exist !
  • Troublesome misunderstanding in communication.

Study case: Comate Bluetooth function helps user to analysis

Here is the common see problems of vortex flow meter during operating:

Situation on the site:

-Vibration: vortex meter based on ”“Karman vortex street”  working theory, is to study the response of  vortices when passing by the shedding body. A vortex flow meter to structural vibrations due to impulsive forces applied on the pipe. Vibration from pipe or mechanical devices around will cause vortex shedding bar obtained fault signals.

-50Hz frequency interference: check the vortex meter have grounded.

For the pulse output type, test with a frequency tester. you can directly measure the negative terminal P and whether the frequency has 50Hz interference. For the current output type, you can test the COM1 and PLS terminals.

Problem from the meter itself

Customer asked, why your vortex meter shows 0? 

A vortex steam mass flowmeter placed on the process line to measure the steam generated by the boiler which was visually confirmed. However, the vortex shedding flow meter in the feed pipe displayed zero flow. We hope can remove it from the service and check in our lab, but users don’t have another one for replacement. Here are the potential problems could cause this issue to occur.

vortex meter installation on site

A, Wiring problem: Seems easy, but sometime customer are forgetting which one is 2-wire system or in 4 wire system;

B, Configuration problem:

C, Flow rate is lower than the meter itself limits: Need to check by increasing the flow rate;

D, Small signal cut-off function is too high;

E, Transmitter or sensor function lost;

Normally we need to go through the manual all the setting over and over, but with Comate Bluetooth software, customer just need to click the Remote-Diagnosis, so Comate team can remotely check the setting of the meter, and also the signal from sensor.

After cross-contrast the configuration with default parameters, there are all correct and setting as for steam measurement program. But signal from sensor is very unstable, sometimes even becomes DC signal which might cause zero readings.

vortex flow meter remote diagnosis

Remark: The blue line is flow signal detect by vortex shedding bar; purple line is vibration signal

There was found the vibration signal are always stay with the flow signal but customer confirmed there is no strong vibration. And we test the temperature, pressure and vortex shedding bar function all response on time.

Which can confirm here is there is flow but no flow shows and vortex flowmeters are not damaged. We assume the problems come from the flow field cause the shedding bar can’t working.

This kind of funk piece might cause the shedder bar create unstable vortexes street.

After removed the obstacle the meter no dropping to zero flow anymore. For stable measurement, we recommend customer to clean the pipe in next maintenance.

Problem occurred and found and solved finally within 1.5 days which save time and money cost for users to a great extend with the help of Comate Bluetooth software.

Remark: The blue line is flow signal detect by vortex shedding bar; purple line is vibration signal

Hot tap drill tool

The hot tap drill tool is the device to help install the insertion type flow meters in like compressed air, Nitrogen system which are non corrosive, and non-explosive environment.

Users can drill a hole and isntall the flowmeters in a quick time and by this tool.
