The King Instrument 7750 series rotameters are 316L stainless steel meters that feature flange connections, all welded construction (no elastomers), and an end to end length of 250mm. A float and tapered tube design on the 7750 Series Rotameter provides longer, more linear scales and the optional Alarms or 4-20mA transmitter adds to its versatility.

The King Instrument 7750 Series Rotameter is available with an optional single or dual inductive slot sensor alarms or a 4-20mA transmitter. Standard scales are available for water and air, and custom scales can be ordered on request. Water capacity ranges from 33GPH to 16.5GPM and air capacity from 2.2 SCFM to 76 SCFM. The rotameter has a 10:1 turndown ratio, ±3% of full scale flow accuracy, and 1% repeatability.

Maximum temperature is 400°F with ambient temperature range of 33 to 125°F. The all-welded 316L stainless steel construction with flange connections provides excellent durability and eliminates the need for elastomers, making it suitable for demanding applications where leak-free operation is critical.
