Please note that instructions have been sent into the Works for 1 Venturi Meter with .250 throat so that we may test the joint between the glass tube and the meter body (which we are afraid is going to give trouble) before ordering the remainder. If the joint proves satisfactory we shall instruct the remainder as soon as possible after we have been advised of it. (Sgd) E.J.J. | ||
