1.2
The BM series bulkmeters consist of three main assemblies, the manifold, body assembly and rotor
assembly, (Figure 2.1). The basic design of all the bulkmeters is similar. The higher rating of the
larger meters is achieved by bolting two or three body casings (capsules) together and fitting double
or triple rotor assemblies with a larger manifold to suit. A calibrating mechanism and Mechanical
Register are also attached to the front end cover. These can be replaced by a front cover
incorporating a pulse transmitter when required for electronic systems, such as Masterload.
