An optional 2-line, 16-character backlit LCD displays the flow rate and the elapsed total readouts.","ValuMass™ inline and insertion flow meters accommodate virtually all installation requirements. The Series 440 insertion style flow meters are available with 6, 12 or 18 long probes (Optional compression fitting for mounting). Other mounting options are available.
