Flow Indicators SDM / SDMKR

Analogue flow indicators for measuring the flow rate of fluids in mobile and industrial hydraulics. The SDMKR is designed with a loading valve for the strain test of the hydraulic system to facilitate precise control of the operating pressure. In addition, this product can also be subjected to a reverse flow direction (without flow rate determination).

Features ? Suitable for Mineral Oil (Aluminium),   HFC Fluids and Water (Brass) ? Designed for in-line installation ? Mechanical flow measurement ? Controlling working pressure with a pressure   control valve (only SDMKR) ? Flow indication in l/min and GPM for Aluminium units,   Brass units have flow indication for Water and Oil   both in l/min ? Aluminium unit: Dual scale ? Brass unit: Single scale ? Thread to connect with pressure gauge (only SDM) Technical Data Accuracy (at a kinematic viscosity of 28cSt): ? Flow: ±4 % FSD ? Temperature: ±2,5 °C / ±5 °F ? Pressure (only SDMKR): ±1.6 % FS* ? Temp. measuring range: +20 °C ... +110 °C /   +55 °F ... +245 °F ? Media temperature   permanent: +80 °C / +176 °F   temporary (420 bar the disks burst and the fluid is by-passed around the valve. The rupture disks (other pressure ranges on request) can be replaced easily. The SDMKR also permits flow in the reverse direction (without flow rate determination).
