LPH Series NON-ADJUSTABLEFLOW MONITOR

Monitor Flows of Corrosive and Non-Corrosive Liquids and Gases

KEY FEATURESCompact, Dependable, Economical

FEATURES• Close On-Off Differential• Visual Indication of Flow with Acrylic Model• No Seals• In Line Vertical Plumbing • Materials: Acrylic, Brass, 316SS or Teflon• Confirms: Normal Flow Conditions • Senses: High Flow and Low Flow Conditions• Output: Switch Contact

APPLICATIONS• Analyzers• Kidney Dialysis • Machines• Micro Biomedical • Machines• Laser Cooling Systems • Bubbler Systems • Pollution Sampling • Equipment

FNPT PORT SIZES• LPH 125 - 1/8” • LPH 250 - 1/8” • LPH 375 - 1/4”

OPERATIONWhen air/water flows through the unit it causes the magnetic piston to move up at the calibration point. This displacement is caused by the pressure differential from the air/water flowing through the unit. The magnetic piston actuates a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the air/water path. Decreasing the flow below the calibration point causes the reed switch to de-actuate.

• Actuation points for air at 68 ° F• and 14.7 PSIA with increasing flow. • Deactuation (decreasing flow) averages 10% less than actuation• (increasing flow). • Flow setting accuracy ±10% of • calibration points shown.• Repeatability ±1%.• Unit will pass greater flows.

OPERATIONAs flow is established upward through the unit and contin-ues to increase, the pressure differential across the magnet-ic piston increases until it overcomes the magnetic piston’s resistance (mass). This force causes it to progress fully upward to actuate the dry reed switch. This is a snap action and occurs in the decreasing mode as well.

OPERATIONA magnetic piston is suspended by therepulsion of a fixed magnet. When fluid flows through the unit it causes the magneticpiston to move against the repulsion of the fixed magnet. The magnet piston actuates anencapsulated hermetically-sealed reed switchout of the fluid path. Decreasing the flow belowthe calibration point causes the reed switch to de-actuate.

OPERATIONWhen no flow is present the free magneticpiston rests on the bottom of the bore, which is in a bypass off the main line. Adjustment of the orifice in the main line creates a small bypassflow to life the magnetic psiton and actuate the reed switch. When flow decreases, the pistonmoves downward and the reed switch deactuates.

LCA Series ADJUSTABLEFLOW MONITOR

Low Cost Flow Monitoring of Corrosive Gases and Liquids

FEATURES• Broad Range of Adjustability • Compact Size• High Resolution• Materials:316SS, Brass or Teflon®

APPLICATIONS• Welding Systems • Analyzers• Vacuum Systems • Cooling Systems

OPERATIONWhen flow is increased, the magnetic piston is forced against a bias spring. As the magnet comes near the adjustable reed switch it actuates, indicating properflow. When flow decreases the spring forces the pis - ton in the opposite direction deactuating the reed switch an indicating a reduced or no flow situation.

• All models field adjustable• Deactuation (decreasing flow) averages 40% less than actuation (increasing flow)• Repeatability ±2%• Correction must be made for attitudes other than horizontal. • Unit will pass greater flows



TEMPERATURE OPERATING RANGE• PVC: 32° to 120° F• 316SS and Brass: 32 to 220° F• Acrylic: 32 to 160° F For other temperature ranges consult factory.

APPLICATIONS• Gas Chromatography• Analyzers• Filter Maintenance • Metering Equipment • Corrosive Chemicals• Gas Generators

OPERATIONWith no flow present, the magnetic piston is held at the ow tube inlet by magnetic repulsion of the fixed magnet at the opposite end. As flow is established the piston is displaced toward the magnetic end plug and a major portion of the flow is bypassed through the flow tube orifce into the annular space. At the adjustment point the magnetic piston actuates the reed switch. On decreasing flow the switch deactuates.

EFV Series ADJUSTABLE EXCESS FLOW VALVE

For Preventing Uncontrolled Flows of Liquids and Gases

OPERATIONFlow enters the unit and makes a right angle tothe outlet port across the nose of a magnetic piston. The piston is held in place by attraction to an adjusting screw magnet. A pressure differential is created by flow across the piston. When the differential is great enough, the piston slides to a seat at the outlet port. The flow rate a t which the piston actuates ca n be changed externally by turning the adjusting screw, thereby changing the piston’s relationship with the flow stream.In this auto reset model after actuation, the piston rests on a metal to metal seat which allows a controlled bleed. To reset the unit, pressure must be equalized on both sides of the piston. If the source is turned off, either upstream or downstream, the bleed will equalize the pressure and the valve will automatically reopen by magnetic repulsion from the fixed magnet located in the valve body.For positive shut-off an elastomer is used on the nose of the piston. When it comes to rest on the seat it provides a bubble tight closure. To reopen the valve there are two options.1. The upstream pipeline must be bled to atmosphere if the line downstream is at atmosphere.2. A by-pass line with an on/off valve must be installed to port the upstream pressure to the down-stream pipeline to equalize the pressure.Our MRS series is available with the by-pass system as an integral part of the unit.• Actuationpointsforairat68°Fand14.7 PSIG.• Corrections must be used for other gases, line pressures and temperatures.Please consult your representative or the factory.

The 125, 250 and 375 series can be mounted in any position. The 500 and 750 series can be mounted in any position except with the outlet port down. We suggest the unit be calibrated in the attitude in which it will be installed. An actuation point approximately 3 or 4 times normal flow rate should be chosen to avoid the valve actuating from initial pressurization of the system and normal surges. If flow is kept constant, an actuation point 10% above the normal rate may be used.

KEY FEATURESControls high pressure excessive flows.


OPERATIONFlow enters the unit and makes a right angle tothe outlet port across the nose of a magnetic piston. The piston is held in place by attraction to an adjusting screw magnet. A pressure differential is created by flow across the piston. When the differential is great enough, the piston slides to a seat at the outlet port. The flow rate a t which the piston actuates ca n be changed externally by turning the adjusting screw, thereby changing the piston’s relationship with the flow stream.In this auto reset model after actuation, the piston rests on a metal to metal seat which allows a controlled bleed. To reset the unit, pressure must be equalized on both sides of the piston. If the source is turned off, either upstream or downstream, the bleed will equalize the pressure and the valve will automatically reopen by magnetic repulsion from the fixed magnet located in the valve body.For positive shut-off an elastomer is used on the nose of the piston. When it comes to rest on the seat it provides a bubble tight closure. To reopen the valve there are two options.

1. The upstream pipeline must be bled to atmosphere if the line downstream is at atmosphere.2. A by-pass line with an on/off valve must be installed to port the upstream pressure to the down-stream pipeline to equalize the pressure.

Our MRS series is available with the by-pass system as an integral part of the unit.• Actuation points for air at 68°F and 14.7 PSIG.• Corrections must be used for other gases, line pressures and temperatures.

FEATURES• Close On/Off Differential• No Seals• EP to 10RA• 316L Stainless Steel Materials• Senses High/Low Flow Conditions• Switch Contact Output• In-Line Vertical Plumbing• Confirms Normal Flow Conditions

OPERATION As flow is established upward through the unit and continues to increase, the pressure differen-tial across the grooved magnetic piston increas-es until it overcomes the small piston’s resis-tance. This causes it to progress fully upward which actuates the dry reed switch. This is a snap action and occurs in the decreasing mode as well.
