leveling base, large orifice for high flowrate measurements, 4 flowtubes (Size No. 1,2,3 and 5), 8
floats (2 in each of the flowtubes), top and bottom Viton gaskets for all Flowmeters, two support
brackets, two mounting rods, two rod clamps, 5 vials for float storage and a Flowmeter cleaning
kit (94040-9026).

DISASSEMBLY AND ASSEMBLY
Each Guarded and Mounted Flowmeter contains a flowtube, which can be removed or replaced
using the following procedure (See Figure 1).
GUARDED FLOWMETER:
1. Unscrew two end bushings.
2. Remove flowtube from plastic guard.
3. Reassemble in the following order:
a. Insert top rubber gasket (P) in upper bushing (M).
b. Screw plastic tube (N) on upper bushing.
c. Insert flowtube (B) into plastic tube until top of Flowmeter seats against rubber gasket.
d. Insert rubber gasket (P) into lower bushing (M).
e. Screw lower bushing (M) into plastic tube until lower end of the Flowmeter seats against
rubber gaskets.
f. Plastic tube will almost completely cover the thread on bushings and provide a tight seal
against the inner rubber gasket.
