There are different ways to access an APL device, below copied and pasted an explanation. Basically, if you want to use an FDT/DTM software download DeviceCare (free, but just for E+H devices) or FieldCare (all manufacturers, for a fee) from E+H website instead of Pactware. The easiest way...

I have some doubts on above statements. Best GWRs radars on the market achieve +/- 2 mm (0,08 inches) in reference conditions. But this is still not sufficient in custody transfer where all standards (API, ISO, OIML) requires +/- 1 mm in refernce conditions or +/- 3 mm on field. Good Custody...

Dear, if you're having a constant inaccuracy when pressurized, with level reading lower than actual, then gas phase compensation will help. But if you're having erratic readings, jumps to 0% or 100% or alarm echo lost, the root cause must be different. Recording some echo curves with software...

Best GWRs manufacturers offer this feature that compensate the slower speed of propagation of the microwaves passing through a gas phase at high pressure and temperature. You don't mention your process pressure and the gas composition but as an example below the deviations at different P and T...

O&G industry is rather conservative and hooked to "good old times" practices: still today differential pressure is the benchmark against more up to date technologies. I don't beleieve any standard states explicitly such limitation Some manufacturers provide radars with double output: continuous...

Mapping has to be performed ideally with empty tank, but anyway at a distance that doesn't cover the real echo -> some 10...20 cm higher. Then, if water splashes directly on the radar's antenna it's not good for the level reading. Before moving to a more robust radar or another technology you...

Q=Av, you have to know area and velocity. If you have a full pipe area is known, so cut it and install a magmeter to measure velocity. If you have an open channel or round sewer drain with a weir or a flume (Parshall, Venturi) to stabilize flow velocity, measure area with a level device, radar...

Different and probably better technologies can be used apart from the ones you already tried. Before the weir, for oil/water interface measurement you can use Guided Wave Radars, best installation is in external chamber using the side-side connections of the DP cell. Depending on kind of...

There are several apps available for the calculation. With products, sensors and barriers, of Endress+Hauser it's extremely friendly the use of ExiCalculator app, free download from App Store or Google Play. The app also generates pdf documents for safety records

For moving from TOV (Total Observed Volume) to NSV (Net Standard Volume) you have to apply several corrections. For a flow measurement the most important ones are the API or OIML or ISO Standards related to volume conversions of various hydrocarbons at specified T and P. Below the most used API...

FMR51 is a radar, not ultrasonic. Check if the Empty and Full values you set in the configuration wizard are correct DC of water is 80, set the parameter to "Water based" If there's a display on the radar, you can see an echo curve on it for checking if there's a false echo at 93% If there's an...

There's a nice app from Endress+Hauser named ExiCalculator that makes calculations based on their sensors models plus cable features. It also print a pdf with results. Just with their products. Downloadable for free from App Store or Google Play

You could try this FWR30 from Endress+Hauser. It's a battery operated 80 GHz radar with a SIM inside that sends data to E+H cloud named Netilion. You get the data via web connection with any fixed or portable device, tablet, smartphone... Cost is sure higher than the empty bottle you used, but...

Instrument manufacturers, at least the most important ones, have special departments for out of standard products. There is a big number of them, such as special process connections or exotic alloys, that are already present in their "specials" database, thus having already price and delivery...

Accuracies of field devices and also of indicators, controllers... listed in technical documentation are intended under reference conditions in laboratories (T, P, humidity, no interference, ideal reflection for radars...) , according to specific norms such as DIN 61298-2 or others. In the...
