Flow Indicators SDM SDMKR
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 lmin and GPM for Aluminium units,
Brass units have flow indication for Water and Oil
both in lmin
▪ 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).
