Titan Flowmeters: Metra Smart - Computation and display of flow meter rates, totals and analogue output
|
The Metra-smart was specifically designed for computing & dis-playing rates and totals as well as giving an analogue output pro-portional to flow. It can also give two pre-set flow switch points and calculate differential rates from two input sensors. The in-strument will display Re-settable Total, Accumulated Total and Flow Rate in engineering units as programmed by the user. Sim-ple PIN protected flow chart programming with English prompts guide you through the entire programming routine greatly reduc-ing the need to refer to the instruction manual. The pulse output can be selected to act as an input pulse repeater serving as a signal conditioner module or may be programmed as a scaled pulse output for remote metering. There is a ten point linearisa-tion for non-linear sensors. The analogue output and flow switch functions requires an external 8 - 24Vdc power supply. The ro-bust housing is purposed designed to suit harsh indoor & out-door industrial and marine environments. It is weatherproof to IP67 (Nema 4X) standards, UV resistant and uses glass rein-forced nylon mouldings with stainless steel screws & viton 0-ring.
Titan Flowmeters: Metra smart - computing and displaying flowmeter 'totals'
The LCD 8 digit alpha-numeric display has 9mm high main charac-ters with engineering units & mode indicators plus a low battery indicator. Displays rate, total and accumulative total all with inde-pendently programmable decimal point positions. The program-ming prompts scroll in plain English for ease of use. The inputs are compatible with reed switch, Hall effect detector, magnetic coil (20mV P-P), Voltage pulse & Namur proximity detectors. Maxi-mum input frequency 500 to 5Khz depending on sensor type, mini-mum 0Hz, (0.1Hz when used on internal power and for rate indica-tion). A loop power of 4 to 20mA can be spanned anywhere within the flow range, 12~24 V dc into 750 loop load. Accuracy is ±0.1% FSD. A test output is activated during programming for a system function check. The two set points are NPN/PNP pulse outputs with selectable FET transistors programmable as high and low set points with dead bands. Maximum power is 100mA at 24V dc. Internal 3.6V Ultra lithium battery is used for internal battery powered use. There is an additional scalebale pulse output se-lectable NPN or PNP it has a maximum frequency of 100 Hz. @ 1A maximum. The housing is high impact glass reinforced nylon with a self drill cable gland in the base or rear. Operating tempera-ture range –20°C to +80°C. When the unit is measuring flow rate the first 2 or 3 digits show the time base i.e. SEC, MIN, Hr or DAY.
