Introduction
The OTC 4291 100 gpm Flow block is included in the OTC 4285 Hydraulic Test Kit which accurately measures flow,
pressure, temperature and speed. The kit is designed for checking hydraulic pumps, motors, valves and hydrostatic
transmissions. This easy-to-use diagnostic unit can pinpoint hydraulic system faults, reduce downtime and help in
preventative maintenance. Main hydraulic circuits, drain leakage flows and dual pumps can be measured simply at
the turn of a switch. The readout can be used in the most convenient position; for example, in the cab of a vehicle,
with the flow meters installed anywhere in the circuit.
