The longitudinal structure function, FL, is identically zero in lowest order QCD, but due to gluon radiation gets a non-zero value in perturbative QCD. Measurements of FL can thus provide constraints on the gluon density in the proton which are complementary to that obtained from the scaling violations of structure function F2. In this report indirect measurements of FL from ep collisions with the H1 detector at HERA accelerator, at center-of-mass energy of 320 Gev, are summarised. For the measurement of the FL it is essential to reach maximum possible values of inelasticity y. Experimental techniques which can provide precise measurements in this region will also be discussed.
