Flow Meters

Universal Flow Monitors

Universal Flow Monitors – high quality mass flowmeters, water flowmeters, lubrication flow meters and air flow meters for both specialized and general applications

Vane or Piston Variable Area Flow Meters

Options – By Control Box Readouts, By Flange Specifications

Our variable-area meters are used in many diverse industries, monitoring flow of water coolants, lubricants, acids, chemicals, solvents, corrosive liquids, delonizde water, sea water, paint, weld-shielding gas, gases, and air.
They flow by the variable orifice principle, as do traditional  rotameters. But rather than pushing a loose float up a tube (against gravity), the flowing liquid pushes against a spring-loaded swinging vane or piston.

• Direct linkage between the sensor and the pointer, makes low-cost switch actuation possible, without magnets.
• No fragile glass or plastic tubes.
• They work with dirty or opaque fluids with viscosities up to 650 centipoise (3,000 SSU).
• They mount in line, in any position. Flow rates <800GPM (3000 LPM), do not require straight pipe runs.
• They can handle shocks or overflow up to 1-1/2 times rated capacities.
• They take higher pressures, in some models up to 2000 PSI(137.93 BAR).
• Operating temperatures from 30° F (-1° C) to 400° F (205° C).

These flow monitors are available in two designs and five sizes. The vane design is made in four housing sizes; the S, the M, the L, and the X, each progressively larger. The piston design is made for measurement of full-scale flow rates in liquids as low as 5 GPH (20 LPH) and as high as 1500 GPM (5500 LPM).

Insite™ Transparent Plastic Flowmeters

These simple, direct reading flow indicators are made from transparent plastic with metal or plastic end fittings. They are used to monitor the flow rate of water or compressed air. The end fitting can be made from brass, stainless steel, aluminum, or PVC. The plastic tubes are made from PVC for water flows 3 to 50 GPM (20 TO 200 LPM), or Polysulphone™ for flows from 5 to 50 GPM (20 TO 200 LPM or 1,400 to 14,000 SPLM) maximum.

The transparent tubes allow the user to read the flow rate from the printed scale where it is intersected by the edge of the float in the fluid. The ses- through construction allows direct viewing of the fluid conditions as well as the flow rate. Switches are available. These monitors install easily in any position.

Variable Area Vane-Style Flowmeter with Filter Flow Switch

FO Series monitors combines a flow rate indicator and switch with a filter. They protect valuable machine tool heads by monitoring the flow of lubrication and filtering any foreign particles that may elude the primary filtration

Sensor Manifolds – Multiple Outlet Flow Manifolds with Sensors

Sensor manifolds distribute flow (through one common inlet and up to 4 outlets of choice) and monitor the flow rate to each branch. Temperature and/or pressure can be monitored as well. The readings are then transmitted to a remote panel (or our OCTOPUS) for control or monitoring functions.

Octopus™ Multi-Channel Receivers

The OCTOPUS a-channel multifunction receiver/controller is for use in systems where accurate flow totalizing and rate indication are required. It accepts and displays such inputs as flow rate, pressure and temperature, rmp, etc. Features include 8 alarms (high, low, or comparative) activating 5-amp, dry-contact, Form C output relays. It provides power to all transmitters.

FlowStream™ Mass Flow Meters for Gas

The FlowStream Mass Flow Meter is ideal for use with gases. No moving parts in an improved laminar flow elements design yield precise, accurate, reliable flow measurement.

The FlowStream measures flows from 1 to 1200 SCFH (1 to 566 SLPM) through a standard ¼”, 3/8”, or ½” inlet/outlet connection, depending on flow range required. Options include digital display, transmitted output of 4-20mA, 0-5 VDC, switching (5 ms response and Nema 4 enclosures). It can be pre-calibrated at the factory for use with these standard gases: air, nitrogen, helium, argon, carbon dioxide, and various other gas mixes.

Mensah™ Readouts and Controls

These devices are available in two series: an integrating totalizer and/or ratemeter, and a batch controller, both suitable for panel-mounting. They accept analog signal inputs, and can be field programmed to accept 4-20mA, 0-5V, 0-10V, 1-5V, or 0-20mA signals. These units have an optional 4-20mA output to control strip recorders or other peripherals. Other options include two adjustable Form C contacts, Square Law input and either a RS422 or RS232 serial communication link for data exchange with a host computer.

Universal Flow Monitors Instrument Panels

Universal’s standards of flow instrument panels offer many advantages over custom-building your own. There is no design-time required and they are ready to use. They are fully-assembled and pre-calibrated. They do require a 115V-60Hz power source, and a standard 4-20mA signal from a Universal transmitter (or other transmitter).
