measurement technology for oil and gas exploration

Turbines form Hoffer Flow Controls are perfect in measuring petroleum, heavy oil, gasoil, diesel, petrol, fuel or jet. Hoffer  has more than 40 years experience in the field of oil and gas measurement and meters for custody transfer. Turbines are available in different accuracy classes. For high accuracy applications we recommend:

For size 1″ to 4″ API Series – custody transfer

The API series flowmeters are specified with an accuracy of ±0.25% of reading over linear flow range and ±0.5% of reading over extended range. Premium meters with ±0.15% of reading over reduced range of 1:5 on request. Repeatability is ±0.02% of reading over repeatable flow range.

For sizes 4″ to 12″  CT Series – custody transfer

Hoffers CT series comes with an accuracy of ±0.15% of reading over linear flow range. Better accuracy over qualified range is available on request. Repeatability of turbines is ±0.02% of reading over repeatable flow range.

For both series bi-directional measurement as well as redundant measurement is available. This option includes a second pickup coil to meet special requirements for oil and gas applications.

Electronics

Turbines require signal conditioning to get an analogue output or a displayed flow value. The electronics HRT1 or HIT-4U can both be used perfectly to compensate turbine signal. Both electronics offer a display, non-resetable totalizer, and linearization.  Explosion-proof enclosure for hazardous area and amplified pickup coil for signal transmission over some hundred meters are part of our portfolio.
