This precision-calibrated orifice is designed for flow balancing in liquid cooling applications where system pressures are below 500 psid. Lohm rates range from 475 to 3100 Lohms. This flow restrictor is 100% flow tested to a +/- 2% tolerance, unidirectionally. Protected in the flow direction by an integral safety screen, the Lee Micro Jet is easily installed into heat exchanger return ports. The restrictor’s small size allows it to be located directly behind quick disconnect fittings.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
