Thanks for the suggestion, EddieM. I found a company which may offer heat meter testing at http://www.rhimetering.co.uk/independent-testing/. I'll give them a call on Monday.

Hello I have found myself in a difficult situation and I hope someone could offer advice. I bought a flat in an apartment building last year. The flat is heated using a district heating system and each flat in the building has a heat meter (mine is Siemens 2WR5), which is used for billing. In...

@MeldrewsMate, it also looks that way to me. I think I managed to isolate the fault, which is, as the meter shows, "operation limit below target". I can't find any explanation on what is causing that error and how to rectify it. Nor I can get a hold of someone who has experience with Landis+Gyr...

That's correct I think. You can see flow rate and temperature differential in Loop 1. Accumulated values are shown in the User loop. While values in Loop 1 are changing, values in User loop are not updating. On top of that the accumulated volume shows 7 m3 which can't be correct. It's been...

The meter is supposed to display the following in the "normal" mode: Accumulated thermal energy and volume are not changing. The meter is connected to the BMS via a pulse output module, that's how the building manager bills me. I haven't tested the actual module for faults.

@MeldrewsMate: The meter is installed on the return line. The flow is therefore negative. The temperature difference is also negative, and the resulting calculation for the energy has the correct sign. I did check the sensors and they're working fine. The meter is also registering the water...

@endecotp - yes, thanks... I should read datasheets more carefully. I connected to the meter via UltraAssist and it appears it correctly registers flow and temperature difference, and calculates the kWh value with a correct sign, see attached picture. However the display still shows an "u" in...

I live in a building with a number of flats, and the heating is provided by a central boiler, which is sort of like a shared asset. We have a building manager who deals with bills but if anything breaks, we pay for it ourselves. And it's the building manager who contacted me with the news that...

Hello The heat meter in my property has stopped working and I am trying to troubleshoot and fix it, if that's possible, before purchasing a new one. The model is Ultraheat 2WR5381-5BC61-0TB2, decoded parameters below: When I enter Service Loop 1, the Current Flowrate and the Current Heat...
