As chaves de fluxo programáveis F29 MK3 estão disponíveis em várias configurações para atender a aplicações específicas. Para fluxos com sólidos em suspensão, veja a opção de fio abaixo.

Opção de fio (trailing wire)

Este controlador pode usar um fio (trailing wire) no lugar da palheta. Peça o F29-S-MK3 / F29-SS-MK3 / F29-S-12-MK3 / F29-SS-12-MK3 junto com um kit de braço com fio da Série TW (TW-ARM-KIT-[comprimento]): são dois itens separados. Isto substitui o TW29, que foi descontinuado.

O kit é fornecido solto e o seu instalador faz a montagem. A Kelco não monta kits nem fornece unidades montadas. As instruções de montagem são enviadas por e-mail com o seu orçamento.

Comprimentos do kit: 50, 80, 100, 140, 160, 180, 200, 250 e 300 mm. Para qualquer outro comprimento, escreva para [email protected].

Encontre os kits em Peças de reposição. Verifique o comprimento para o seu tubo na Calculadora de palheta.

Programming lock—
Remote start (momentary)Remote start via an external switch closing its contacts (momentary closing) — a pressure, temperature or level switch or a set of external relay contacts.
Remote start and stopThe F29 only runs the pump while the external switch is closed. The external switch can be a tank level switch, a pressure or temperature switch or a set of external relay contacts.

Front and side views with key dimensions (mm). 1" BSPT thread connection; paddle is cut to suit application.

Flow Sensitivity

The flow rates required to actuate the F29 MK3 Series flow switch depend on many variables — turbulence, liquid viscosity, and the exact area of the paddle face exposed to the flow. For an accurate estimate of switch performance and to determine the effect of paddle trimming, use our online paddle calculator.

3-Phase Pump Motors

The F29 MK3 switches can be used to control either single-phase or 3-phase pumps, provided a 220–240 V AC or 24 V AC supply is available at the installation site. For 3-phase motors the F29 drives an interposing contactor which switches the motor itself — see the Pump Controller Power Calculator to size the contactor and check cable/voltage drop.

Application Restriction

The F29 MK3 is an industrial control device, specifically designed for use in industrial, agricultural and mining applications. It must never be used for any other application. Installation must be carried out by a qualified pump engineer, and all electrical work by a licensed electrician.

Hazardous Areas

The F29 MK3 is not certified for use in hazardous areas and must not be installed in any area classified as hazardous under AS/NZS 60079.10 (Zone 0, 1, 2, 20, 21 or 22). Suitability of the F29-D models for diesel refers only to the chemical resistance of the wetted materials. Where a pump handles flammable liquids, the controller, which has its flow sensor built in, must be located outside any hazardous area.

Manutenção

As chaves de fluxo programáveis F29 MK3 não estão sujeitas a manutenção pelo usuário. No entanto, peças de reposição — incluindo palhetas e conjuntos de parte úmida — estão disponíveis no seu distribuidor local ou diretamente na Kelco Engineering.
