BEKA associates have introduced third generation Rate Totalisers which provide an easy to read display of rate and total flow in the same or different engineering units from almost any pulse output flowmeter. They include the features and functions most frequently requested by users during the past ten years, including two inputs, linearisation, smaller enclosures for applications where panel space is limited and even larger digits in the 144 x 72mm models. A rugged 316 stainless steel model is included for use in marine environments. All models have IP66 front of panel protection. Options include an internally powered display backlight, isolated synchronous pulse output, isolated 4/20mA output and dual alarms.
In addition to general purpose instruments, intrinsically safe models have ATEX, IECEx, US and Canadian certification allowing worldwide installation in gas and dust hazardous areas. For applications in Zone 2 or 22, Ex nA and Ex tc approval permits installation without the need for Zener barriers or galvanic isolators which significantly reduces installation cost.
Although well documented and easy to configure on-site, these rate totalisers can be supplied configured to customer’s requirements with a slide-in scale card showing the customer specified units of measurement for no additional charge.
All BEKA instruments are supported by a three year guarantee and for customers wishing to evaluate an instrument on-site, a free three month sale or return evaluation service is available.
