Flow Monitors SU1003 / SU1004 Description Single point flow monitor (SU 1003), dual point flow monitor (SU 1004), with change over MIN/MAX monitoring function, suitable for water, oil, air and media with similar thermal conductivities. With either no delay, or with a 60 seconds switch on delay or 10 seconds change over delay (SU 1003). Features � Adjustable to wide range of flow rates � No moving parts in the flow stream 1 � Operation largely independent of pipe diameter � LED status indication � Fast response time � MIN or MAX switch point � Suitable for all media (water, oil, and air) � Cast aluminum weatherproof housing SU1003 Technical data General data SU1003 SU1004 Single Point Flow Monitor Dual Point Flow Monitor Media liquids, gases liquids, gases Monitoring flow rate 1 switch point (MIN or MAX) 1 or 2 switch points (MIN and MAX) function medium temperature 1 switch point (MAX) Display flow rate 1 dual colour LED 1 or 2 dual colour LED’s (red/green) Temperature medium and monitoring head -25 °C...+70 °C (-13 °F...+158 °F) -25 °C...+70 °C (-13 °F...+158 °F) range electronic control unit -25 °C...+50 °C (-13 °F...+122 °F) -25 °C...+50 °C (-13 °F...+122 °F) Electrical data Input voltage AC 230, 115, 24 V 50/60 Hz AC 230, 115, 24 V 50/60 Hz +10 %, -15 % +10 %, -15 % DC 24 V ±20 % DC 24 V ±20 % Power consumption approx. 1.2 VA approx. 1.5 VA Relay outputs flow rate 1 change over contact 1 or 2 change over contacts AC 250 V/DC 30 V, 5 A AC 250 V/DC 30 V, 5 A medium temperature 1 change over contact AC 250 V/DC 30 V, 5 A Flow monitoring Flow response level adjustment with gases: 0.5 m/s...50 m/s (2 to 160 FPS) (steplessly by means of a potentiometer) with liquids: 0.01 m/s...2 m/s (0.03 to 7 FPS) (1) Repeatability ±10 % (2) Response delay 2 s with water, 4 s with oil, 7 s with air selectable delay (no delay, 60 s switch-on delay or 10 s change over delay) Switch point drift through temperature change of the medium approx. ±0.7 %/°C (±0.4 %/°F) Mechanical data Type and size of monitoring head 1/2"NPT, 3/4"NPT, 1"NPT (3) Pressure resistance of monitoring head 250 bar/3675 PSI Environmental monitoring head IP67 protection electronic control unit cast aluminum weatherproof FM, CSA approved housing fitting/sensor support stainless steel 1.4571/AISI 316Ti Materials sensor stainless steel 1.4571/AISI 316Ti sealing nickel based solder DIN 8513-L-Ni electronic control unit Epoxy painted cast aluminum Housing electronic control unit 4.5" x 4.5" x 3.5" dimensions Cable length standard without max. length 100 m (1) of the set value, at constant temperature and flow conditions, and stable thermal conductivity.

If mounting, switch configuration or sensor material is other than shown in the ordering information please consult factory for pricing and availability. 2.) A Pipe thread size adaptor is supplied for 3/4"MNPT and 1"MNPT process connections as shown in the chart in the above dimension drawing and is used with a Process Connection Code ”050“ probe in all cases. A Sensor Material Code ”A“ probe is shown in the above drawing. If insertion length is other than noted, please specify. Insertion length = from tip of probe to the start of the insertion threads or flange. 3.) For optional remote electronics only. Enter code followed by number of feet (Example: 1-6=6" PVC Cable) * Field Selectable ** Time delay is inactive in standard unit *** Type SU 1003 only **** Type SU 1004 only. Field Selectable. Setpoint ”B“ Only. Standard factory setup is Setpoint ”A“ = low setpoint for flow (fixed) & Setpoint ”B“ = high setpoint for flow. Setpoint ”B“ can be changed by jumper selection to be a temperature switch. 2 www.e-t-a.com 05/06(040505) see note 2 “B” -+-+ R GR G 4.5 Flow Monitors SU1003 / SU1004 Connection diagram Remote electronics SU1003 Terminal Block inside Junction Box 5 = SU1003 8 = SU1004 1 G R LED L N MIN/MAX Junction Box 50’ Cable 1 2 3 4 5 flow 3/4’’ FNPT potentiometer Sump or Pit Floor Level SU1004 MIN MAX Liquid = Water G R R G LED L N Sensor flow potentiometer 1 2 3 4 5 6 7 8 MIN MAX All dimensions without tolerances are for reference only.
