FLOWTELL" in-line flow monitors and controllers

Stauff’s "FLOWTELL" in-line flow monitors and controllers offer a range of rugged flow rate gauges that are accurate and economical and are the perfect instruments for fixed in-line monitoring or for use as service tools for system commissioning.

"FLOWTELL" employs the well-established and reliable ‘variable area orifice’ measurement method together with a unique ‘sharp edge technology’ that ensures low pressure drops and high tolerance levels to changes in viscosity, resulting in repeatable flow rate measurements for both liquids and gases.

The product range is suitable for measuring Hydraulic Oils, Water and Air or Gas mediums and includes models for Phosphate Ester. A special range is also available for High Temperature applications. "FLOWTELL"’ is also available with the option of field-adjustable single or twin switches for High and Low flow rate alarms, or as a Transmitter giving a 4 - 20mA signal for system control capability.

Flow Indicator

Flow Indicators are designed for continuous monitoring or intermittent use commissioning and servicing hydraulic systems up to 420 bar, 6000 psi.

The large clear 63mm diameter dial ensures that quick checks can be made to determine pump performance and setting of flow control valves. They can be used on mobile and industrial hydraulic circuits. Also lubrication and coolant systems using oil/water.

 Flow Indicator FI Aluminium with Temperature (246KB )

The RFI reversible flow indicator is designed for continuous monitoring or intermittent use commissioning and servicing hydraulic systems to 420 bar.

 Reversible Flow Indicators - FI with Temperature (188 KB )

Flow indicators also available in Bronze

Bell Housings and Couplings

Stauff Bell Housings & Couplings are designed to connect pumps to electric motors, B5 standard.

There are two series available, the first to suit metric, 4-bolt mount, pumps from Group 0.5 to Group 3 and the second to suit SAE, 2-bolt mount, pumps from Group AA to Group C. The coupling halves are pre-bored and keyed to suit standard motor and pump shafts. The complete coupling comprises the pump hub, the motor hub and the rubber spider.

Bell housing selection is related to the "frame size" of the drive motor and the pump group designation. Selection of the bell housing and the coupling set can be simply read from the tables on page 4. of the Bell Housings and Couplings catalogue.
