Capacitance Level Definitions

High Level Fail Safe (HLFS):

Relay de-Energizes on High Alarm condition. Thus the alarm condition with power failure.  Example: To Keep tank from overfilling with power failure.

Low Level Fail Safe (LLFS):

Relay de_Energizes on Low Alarm Condition. Thus alarm condition with power failure. Example: To Keep pump from running dry and burning up with a ower failure.

Time Delay:

Used for Splashing or wavy processes to prevent cycling on and off.

Response Time:

How fast the unit goes to alarm condition after set point is reached.

C, NO, NC Contacts:

Contacts are normally shown in the non-energized alarm condition – no power, shelf condition.  Relay energizes in non-alarm condition.

POINT LEVEL

ZERO:

This is the SET POINT. Where the desired actuation is to occur.

DIFFERENTIAL:

This is the distance, in Pico-Farads, inches or feet from ZERO to where the RESET is to occur. Sometimes called Deadband or Pump On – Pump Off.

CONTINUOUS LEVEL

ZERO:

The 0% Level point on the sensing probe.

100%:

The full level point on the sensing probe.

SPAN:

The distance in Pico-Farads, from the Zero Level point to the FULL Level Point (100%).

TERMINAL CAPACITANCE:

The Minimum amount of Capacitance present when no product is present in the vessel.

This is:

The Capacitance of the Probe Gland (and sheath and colling extension, if used) PLUS

The Capacitance generated between the probe and the vessel with air as the dielectric. In other words, the absolute minimum value of capacitance generated in that particular probe/vessel installation.

TERMINAL / SPAN RATIO:

The Terminal Capacitance divided by the span capacitance. This ratio must not be exceeded where specified on product specification sheets (all instruments do not have this restriction).

Terminal Adjustment/Zero Adjustment Range/Maximum Zero Suppression:

This is the maximum “Zero Suppression” of the capacitance value at the zero point level in the vessel.  This value cannot be exceeded.

Capacitance Change:

The amount of capacitance difference between ZERO and 100% points in the continuous level measuring instruments; the amount of capacitance difference between product and no product in point level measuring instruments without differential; or the amount of capacitance difference between ZERO and Differential points in Point Level measuring instruments with differential adjustment.

TOTAL CAPACITANCE:

This is the total capacitance value (not capacitance change) with tank of vessel at the 100% level (includes terminal capacitance). This value must not exceed the maximum span of the instrument.

Materials:
Bronze, Ductile Iron, Carbon Steel, Stainless Steel, PVC, PP, PVDF
Wide variety of special materials also available  

Penberthy jet pumps can also use steam or a gas (air) as the operating media for exhausting, evacuating or priming operations. Primary uses of these types of pumps are for exhausting or evacuating gases. Exhausting means removing gases from an area at a continuous rate while maintaining pressure at a constant level. Evacuation means drawing gases from a defined volume by pumping the vessel down from an initial pressure to a final lower pressure. These steam/gas motive jet pumps meet the industry's most stringent requirements, while providing a simple, low-cost method of transporting gases, operating flawlessly even in the harshest work environments.

Penberthy Models GL and GH operate at pressures from 20 to 120 psig (140 to 830 kPag), the overall capacity being slightly higher when using air as the operating media. U and L Models are single-stage ejectors while the 2NC is a two-stage, non-condensing ejector using steam as the operating media. All these units provide maintenance-free pumping capabilities.

Some uses for steam/gas motive jet pumps include: creating vacuums, exhausting vapors from process systems, evacuating tanks & vessels, priming, fume removal, fluid concentration, humidifying and drying. Industries that could benefit from the use of the jet pumps might include: chemical processing, textile manufacturing, food processing, petroleum production & refining, sterilization and HVAC.

Typical applications involve either exhausting or evacuating. Similar information is needed in order to determine the specific jet pump for your application. Using the information required (listed below), fill out an application form and submit to Penberthy sales representative or the factory to determine the correct pump for your needs.

If Exhausting (Continuous Suction Flow) Motive: Gas/Steam Pressure (Available) Flow Rate (Available volume-scfm) Temperature Molecular Weight (Gas only) Suction: Pressure (Inches Hg Abs-kg/sq cm Abs) Flow Rate-scfm Temperature Molecular Weight Discharge: Pressure (That unit must overcome) If Evacuating (Sealed Vessel-Pump Down) Volume of Space to Evacuate Required Evacuation Time (Minutes) MOTIVE: This function is the power phase of the pumping operation. At this stage, the velocity of the motive media increases as it passes through a nozzle. This phase of the pumping operation takes advantage of the kinetic properties of the motive media, whether it is liquid, steam or gas. Because of this, design differences may exist within the motive connection of the jet pump. For instance, jet pumps with liquid motives use a converging nozzle, since liquids usually cannot be compressed. On the other hand, jet pumps with gas or steam motives use converging/diverging nozzles to achieve trans-sonic flow velocity. The critical flow paths of all Penberthy jet pumps are smoothly machined with no abrupt turns or steps in order to produce the most efficient flow during the motive function. Without this direct flow design and smooth interior surface, the jet pump would not operate at peak efficiency. SUCTION: This connection of the jet pump is where the pumping action takes place. The high velocity stream of the motive causes a drop in pressure in the suction chamber. This allows pressure in the suction vessel to push a liquid, steam or gas into the suction chamber of the jet pump. This, in turn, is entrained by the high-velocity motive stream emerging from the inlet nozzle DISCHARGE: As the motive flow combines with the suction medium, some kinetic energy of the MOTIVE is transferred to the SUCTION, mixing and discharging at a reduced pressure. The amount of pressure that can be recovered depends on the ratio of the MOTIVE flow to SUCTION flow, plus the amount of SUCTION pressure built up in the suction vessel. Kinetic energy is converted back to pressure as the mixed media passes through the diverging taper and is discharged out the pump.

GL series jets have a motive pressure range of 60-120 psig and suction range of 6-30 inches.
GH series jets have a motive pressure range of 20-80 psig and a suction range of 6.5-30 inches.
Cast eductors can be made from 1/2 inch size to 4 inch size.
Fabricated eductors are 4 inches and up.
Non-Metallic are 1/2 to 3 inch size, these are PVC, Poly Pro, and Kynar.
