King Instrument Company

King Instrument Company At the time we occupied a 1200 square foot space in a multi-tenant building. With two small manual lathes, a cut-off saw and two drill presses we began production.

About King Instrument Company

The product line consisted of a total of 21 model numbers. In our first year of business sales were just over $37,000. A lot has changed over the years. We now run two shifts and utilize the most sophisticated computer controlled machinery. King Instrument Company currently calls its home a 46,000 square foot facility in Garden Grove, California. We now manufacture 95% of the 6000 meter components used in our products.

These include the borosilicate glass metering tubes we call Kinglass. We operate an in-house calibration lab and perform NIST traceable calibrations (conform to ISA RP 16.6). The King product line has grown and expanded to satisfy the demands of almost any variable area flowmeter application. King Instrument Company are sensitive to their customer’s requirements. In fact nearly all our products were designed in response to customer need with our own exceptional quality and distinctive style.

All 316L stainless steel construction with flanged connections makes this meter suitable for low-flow, high-pressure applications.

Stainless Steel Tube Flowmeter 7710 Series

This all 316L stainless steel meter utilizes a float and tapered tube design which offers longer, more linear scales, better pointer stability and 40% greater accuracy than competitively priced products. A 4-20mA transmitter option adds to its versatility.

7750 Series Stainless Steel Tube Flowmeter

These 316L stainless steel meters feature flange connections, all welded construction (no O-rings), and an end to end length of 250mm. A float and tapered tube design provides longer, more linear scales. A 4-20mA transmitter option adds to its versatility.

7459 Series – Glass Tube Flowmeter

Expanding the line of side plate construction rotameters, King introduces its 7459 Series. These models feature a 250 mm scale borosilicate glass tube with aluminum side plates and a polycarbonate shield. Connections are vertical FNPT, 316L stainless steel.

7460 Series – Glass Tube Flowmeter

There is nothing else like it in the industry. This 75 mm scale glass tube meter offers economical 304 stainless steel case construction with vertical connections.

7470 Series – Glass Tube Flowmeter

Available with NPT or flange connections, vertical or horizontal, this 127 mm scale glass tube meter offers value and versatility in 304 stainless steel case construction.

Acrylic, Polysulfone & PVC Flowmeters

7200 Series – Acrylic Tube Flowmeter

A real value in general purpose rotameters. Vertical connections are from 3/8″ NPT to 2″ NPT.

7330 Series – Polysulfone Tube Flowmeter

Union ends simplify installation and maintenance. With the Teflon® float option these meters are excellent for applications where no metal is preferred. Socket weld end connections are available

7310 Series – Polysulfone Tube Flowmeter

An economical 304 stainless steel case with a molded polysulfone metering tube for lighter duty applications where a case enclosed meter is preferred.

7510 & 7511 Series – Acrylic Tube Flowmeter

Acrylic block construction with direct reading scales have white screen printed backs to enhance scale readability. Connections are in-line for easy installation.

7520 & 7530 Series – Acrylic Tube Flowmeter

Economical machined cast acrylic block construction makes these flowmeters great for OEM use. Optional inlet metering valve available.

7720 Series – PVC Tube Flowmeter

Type 1, Grade 1 PVC tube meters offer chemical resistance. The dial type display makes measuring opaque fluids  simple. A 4-20mA transmitter is optional.

Alarm Options

  • 7100 Inductive Slot Sensor
    • All 7100 Series flowmeters may be fitted with one inductive slot sensor.
    • Inductive sensors are 2-wire, DC low current devices and are designed to be used with a remote barrier/switch isolator capable of powering the sensor and providing the desired switching option(s). Barrier/switch isolators are available with 220 VAC, 110 VAC or 24 VDC supply voltage requirements, contain single pole, double throw (SPDT) relays, and are DIN rail mountable. (Only 24 VDC units are actually powered by the rail.) See barrier/switch isolator specifications for electrical connections and further details.
  • Inductive Slot Sensor available for 7710, 7720, 7750 Series
    • All 7710, 7720 and 7750 Series flowmeters may be fitted with one inductive slot sensor.
    • Inductive sensors are 2-wire, DC low current devices and are designed to be used with a remote barrier/switch isolator capable of powering the sensor and providing the desired switching option(s).

  • Latching Reed Switch
    • Latching Reed Switch Alarm available for 7310, 7330, 7470, 7480, 7610, 7910 Series
    • A latching reed switch is available for 7310, 7330, 7470, 7480, 7610, 7910 Series flowmeters. Operating temperature range is -40° C to 125° C.
    • The switch assembly is mounted on the side of the metering tube by a dovetail or guide rod. The switch can be positioned to trip at any point on the scale.
    • The switch is a reed type and uses a biassing magnet to give it the latching feature. The float contains hermetically sealed magnet(s), so when the float comes in close proximity to the switch it closes and remains closed (latched) when the float moves past the switch. When the flow returns to normal and the float moves below the switch it resets itself. Multiple switches can be used.
  • INDUCTIVE RING SENSOR
    • Inductive Ring Sensor Alarm available for 7430, 7440 Series
    • Inductive Ring Sensor 7440 Series flowmeters with metallic floats can be ordered with an inductive ring sensor that is able to detect a predetermined rate of flow and is compatible with stainless steel or Carboloy floats only. Inductive ring sensors are 2-wire, DC, low current devices and are designed to be used with a remote intrinsic safety barrier /switch isolator. Sensors are available as either proximity or latching devices. The sensor can be positioned to trigger at any point on the scale. It is able to detect the metal float by producing an electromagnetic field that senses the float within its sensing zone.
