FTB Series totalizers are typically used in applications where accurate measurement of (#2, 4 or 6) heating oil flow is required. The FTB-32 features a fully rotatable, easy-to-read face. The FTB-30 is designed to be mounted horizontally; both the FTB-30 and FTB-31 are shipped complete with mounting brackets and compression fittings, while the FTB-32 is supplied with ¾" NPT couplings. All FTB totalizers are non-resettable. In addition, all FTB-30 Series meters have an optional reed relay scaled pulse output (with 3 m (10') of cable) for remote totalization. This output must be specified at the time of the order; it is not field installable.
