Product Highlights

The SPP638 Flow Meter is a versatile and reliable solution for measuring and recording the flow of various media such as liquids, gases, or loose materials. Housed in a durable and tightly sealed wall-mounted enclosure (IP 67), this flow meter features a large LED display with six digits, ensuring easy readability. Designed to work in conjunction with flow transducers equipped with analogue input, the SPP638 accurately measures both instantaneous flow values and total flow. With a wide range of total flow indication, reaching up to 16 digits, it allows for precise control over flow values during extended operation periods. The flow meter’s batcher function further enhances its usability across a variety of industries, including food, pharmaceuticals, and paint and varnish. The counter offers versatile programming options for the REL / OC control outputs, enabling customisation based on instantaneous flow, batcher, or total flow values. Additionally, customers have the flexibility to select from various analogue outputs, such as active current, passive isolated current, or active voltage outputs. Configuration can be conveniently performed through the remote controller, local keyboard, or free S-Config software using the RS-485 communication port, eliminating the need to open the case.
