Liquid flow calibration
Errakal has two facilities for calibrations of flow meters with liquids, which discriminate in size, DN 80 and DN 300. See specifications below.
| Description | ≤ DN 80 | ≤ DN 300 |
| Flow | 1 ÷ 60 m3/h | 3 ÷ 600 m3/h |
| Liquid temperature | 20 ÷ 70 ºC | 20 ÷ 70 ºC |
| Ambient temperature | 20 ± 3 ºC | 20 ± 3 ºC * |
| Pressure (depend on liquid) | 8 – 10 bar | 7 – 10 bar |
| Available length | 6 m | 8 m |
| Liquids | viscosity (cSt) | viscosity (cSt) |
| Water | 1 (20ºC); 0.7 (45ºC); 0.4 (70 ºC) | 1 (20ºC); 0.7 (45ºC); 0.4 (70 ºC) |
| Sugar solution | up to 70 | up to 70 |
| Glycol | up to 200 | n.a. |
| Primary standard | Prover loop / Weighing scale | Prover loop / volume vessel |
| Working standards | DN 25 Pd meter | DN 50 turbine meter |
| DN 50 Pd meter | DN 100 turbine meter | |
| Accuracy | Better than ± 0.1 % | Better than ± 0.1 % |
| Piping material | Stainless steel | Stainless steel |
| ))* = in the summer the maximum ambient temperature can be 28 ºC with a liquid temperature of 70 ºC | ||
