SPP-94 Low Cost Totalising Digital Panel Meter with analogue input.

SPP-94  flow indicators giving instantaneous flow and totalised flow. SPP-94 is  designed to work in tandem with the pulse flow transducers with current input of 0-20 mA or 4-20 mA. Wide range of total flow (up to 16 significant digits) enables flow volume control for a long time. Build in a batcher function makes possible application of SPP-94 in a wide range of industry branches (food production, pharmacy, paint and varnish). The REL / OC control outputs can adjust the level of measured signal and are controlled according to one or two threshold values. Moreover, the meter can be equipped with analogue outputs, according to the customer selection: active current output, passive isolated current output or active voltage output. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
