U N I V E R S A L ® F L O W MAX FLOW SIZES FROM 5 GPH to 20 GPM (20 LPH TO 75 LPM) MAX LIQUID PRESSURE 150 PSI (10.3 BAR) Flow rate indicator with switch(es) or transmitter LL WATER M O N I T O R S Flow meters, Flow switches and Flow transmitters For Water ® CSA Certied NRTL/C LL Series, with standard scale and pointer (control box A). NRTL/C CE Marked (as noted) NIST Traceable Calibration Certicate Available DESCRIPTION These variable-area meters position an orice over a tapered shaft to establish ow rate. Mounting is in-line and in any position. Straight pipe runs before or after this monitor are not required. The all-mechanical sensing system directly drives the pointer and remote signaling devices. Readout is visual with a pointer and scale combined with switches and a 4-20 mA transmitter. CALIBRATION CONSTRUCTION MATERIALS This meter is congured for water. Brass/polysulfone body with brass and 316 SS internal moving parts and Buna-N seals. LINE CONNECTION The ports are threaded, can be NPT or SAE straight-threads from 1/8 to 3/4 inch. Metric threads such as BSPP or BSPT are also available. The upper port (inline) has a maximum capacity of 2 GPM and the lower port (offset) is standard for the remaining ow rates. All ow meters are individually calibrated for water. For NIST Traceability please consult factory. NOTE: This is a simplied model code and does not include standard options like other materials of construction, internal moving parts, seals, anges, pressure ratings, multiple switches etc. which can be found in other catalog sheets. 1 Fluid ow causes a spring-loaded piston A having a circular opening at its center B to move along the axis of a precision-tapered shaft C. This creates a variable orice in direct proportion to the ow rate. The piston is mechanically linked to the readout pointer D and actuates switch E or a pot driven trans-mitter (not shown).
