Kobold KDF and KDG now also available with shorter installation length

With low volume flow meters and monitors model KDF/ KDG, low flows may be monitored in a reliable  and cost-effective fashion. In addition to the models already introduced in the market for years, this series  is now also available with shorter installation  length  of 90 mm. 

The instruments that operate on the suspended float principle with a stainless steel ball are available in special versions for liquids and gases (air). The devices with stainless steel housing are installed vertically with flow direction from bottom to top via ¼” thread or hose connection of 8 mm diameter. The needle valve enables an optimal setting of the flow rate. The respective flow rates can be read quickly and easily by a direct view of the measuring tube made out of rugged borosilicate glass.

The KDF-9 version for liquids is available with 11 standard measuring ranges from 0.02…0.25 l/h up to 10…100 l/h for water. The KDG with 12 measuring ranges from 2…20 Nl/h up to 300…3000 Nl/h for standard air can cover many applications. In addition to the standard measuring ranges on stock, the devices can be customized for almost any other media, operating pressure and operating temperature. Optionally fitted with ring type proximity switches, preset flow rates can be contactless monitored from the outside.

The meters with differential pressure controller, that can be supplied with upstream pressure controller or downstream pressure controller, are a simple and practical way to keep the flow rates constant. In the robust stainless steel housing, a valve with diaphragm made of FPM or PTFE ensures that the flow rate is kept constant in the preset range.
