INSTROTECH, a Comtest Group Company, has on offer 3 Kobold oval wheel flowmeters, that give precise flow measurement for all viscous, non-abrasive clean liquids, and can be used in a number of diverse applications, such as measurement of fuel consumption for small aircraft, motorboats, and mobile power generators. Applicable media are all viscous, non-abrasive clean liquids, like petroleum and other fuels (including diesel), oil and grease, ink and pastes, and chemicals.
KOBOLD DOE is a low cost, compact, stainless steel body, the Kobold DOE measures fuel consumption for OEM customers, offering different pulse output options including one to measure pulsating flow from peristaltic pumps. Temperature measurement enables appropriate electronics to compensate for changing densities of the liquids of up to 1000 cP, and the unit is accurate to + 1% of readings under reference conditions.
Kobold DOE features:
· Measuring ranges: 0.5 ... 40 l/min
· Pressure max: 64 bar; Temp max: +100 °C
· Specifications: pulse output, integrated Pt 100 (measuring of fuel consumption)
KOBOLD DON –is a high-end, positive displacement flowmeter, with two oval geared rotors that measure a constant volume per rotation within a precisely machined measuring chamber. With each rotation, a constant volume of liquid is measured. The rotation of the oval gears is sensed via magnets embedded in the rotors and transmits a high-resolution pulse output. This signal can be processed externally via a remote display controller or PLC, or other available accessory options attached to the flowmeters. The Kobold DON can be used for liquids with different viscosities of up to 1000 cP and higher on request and is accurate to + 0.2% of readings.
KOBOLD DON features:
· Measuring ranges: 0.5 ... 2500 l/min
· Pressure max: 100 bar; Temp max: 150 °C (High temp version)
· Specifications: all typical outputs, digital display, mechanical register, ATEX and IECEx
KOBOLD DON-H for High-pressure features:
· Measuring ranges: 0.5 ... 40 l/min
· Pressure max: 400 bar; Temp max: 120 °C
· Specifications: all typical outputs, digital display, ATEX
