The King 7440 series flowmeter builds on the 7430 series to offer a more economical low flow metering solution. Suited to purge metering and chemical dosing applications, the 7440 series rotameter offers a Borosilicate Kinglass metering tube and stainless steel. Internal components vary dependant on flow rate and may include 316L stainless steel, black glass, sapphire, Carboloy or tantalum. The 7440 is only available with ¼” NPTF connections with the option of 316L Stainless Steel or PVDF fitting materials.
Viton® O-Rings are standard with optional Buna N, EPR and Kalrez®.
The 7440 series flow meter is available with either a 65mm or 150mm scale and is suitable for both liquids and gases.
All models have a 10:1 turndown ratio with 1% repeatability, accuracy varies by model but this is within a ± 4% (for 150mm scaled version) to ± 6% (for 65mm scaled version) of full scale.
Maximum temperatures are available up to 93° C for liquids and 121° C for gases, with pressures available up to 13.7 bar.
Liquid models are available with full scale flows from 0.75 CC/Min to 1800 CC/Min (0.042 litres per hour to 110 LPH).
Gas models are available with full scale flows from 66 CC/Min to 70000 CC/Min (4 litres per hour to 4200 LPH).
Scales are available in any volumetric unit and optional alarm switches which include a Fiber-Optic NPN or PNP (Proximity) or inductive ring sensor (Proximity or Latching).
