Safety Instructions
General Description
The Sotera 825P and 850P Meters are nutating disk,
positive displacement meters that use magnetic coupling
to convert uid ow into digital display information. The
meter can store and display the current total,or cumulative
total in any of ve programmed units (ounces, pints,
quarts, liters, and gallons) or special units (e.g. per acre
volume). The meter can be calibrated without dispensing
uid by selecting a calibration factor from the 20 stored
settings. Power is supplied by two CR2032 batteries that
can be replaced in the eld. 825P / 850P models feature
pulse output and 4-20ma output for connection to uid
management systems and batch controllers for the control
and monitoring of dispensed uid.
Technical Information
Not for use with uids that have a ash point below
100°F (37.8°C, ie: gaso line, alcohol). Refer to NFPA
325M (Fire Hazard Properties of Flammable Liquids,
Gases, and Vola tile Solids) for ash points of common
liquids. Static electricity buildup and discharge could
result in arc and explosion!

Calibration Procedure using CAL Factor
A) Set CAL factor to 10.
Hold button 3 for three seconds. Press 3 again until the number 10 shows below “CAL” (NOTE: If you go past 10 keep pressing 3 because the number will return to 0 after passing 19). Press 2 to get back to normal operating mode.
NOTE: If your uid is listed on Table 1, use that number in step A above in place of 10.
B) Prime pump and meter by dispensing 2 - 3 gallons of uid back into the bulk tank. With the outlet valve closed and the pump still running, reset the meter to 0.00. C) Fill the Proving Can exactly to the 5.0 gallon line. Focus on the Proving Can, do not look at the meter at this point. Keep the hose end nozzle wide open as long as possible for best accuracy.
D) Adjust Meter CAL Factor. • If meter reads high, increase the CAL factor.
Each CAL # changes the accuracy by about 1%. For a 5 gallon proving can, 1% = 0.05 gallons.
• If 5.10 is displayed, this is 2% over 5.00; the
CAL factor should be changed to CAL 12.
• If the meter reads low, lower the CAL factor. For
example, if 4.90 is displayed, it is 2% less than 5.00, so the CAL factor should be set to 8.
• When nished with the CAL factor procedure,
press 2 to return to normal mode and to reset the meter to 0.00. The meter is now calibrated and ready to use.

Calibration Procedure

Batteries
NOTE: Low battery icon will appear when batteries
require replacement. Meter still functions properly for
several days after the icon appears. Neither calibration,
current total or totalizer quantities will be lost when you
replace batteries.
To Replace Batteries (refer to exploded view).
1. Unscrew meter cap (item 1, page 10). Use a strap
type oil lter wrench or large 5" jaw pipe wrench if
needed.
2. Insert a at-head screw driver into the top slot (see
Figure 4) and gently pry up electronics module.
CAUTION: DO NOT get uid or dirt in electronics area.
3. Remove old batteries and insert new batteries,
making sure battery polarity is correct, or meter damage
could occur (positive side facing up when installed).
4. As noted in Figure 5, reinstall O-ring on electronics
module. Align sensor receptacle in proper location. Press
module gently down into meter cover.
5. Thread on meter cap until hand tight. To check
tightness, there should be approximately 1/16" gap
between cap and ridge on outlet port. (See Figure 6).
Repair
If any meter components are damaged, they should be
replaced. See meter kits drawing on page 10 for correct
replacement part information before ordering.
Maintenance
CAUTION
Follow uid manufacturer's recommended procedures for
handling and disposing of metered uids.
Meter should be ushed between uses with water to
prevent chemicals from drying and plugging meter.
Thorough Cleaning (refer to exploded view)
If meter is plugged due to hardened chemical or debris, do
the following:
1. Drain all uid from meter.
2. Unscrew meter cap (item 1, page 10). Use a strap type
oil lter wrench or large 5" jaw pipe wrench if
necessary.
3. Insert a at-head screwdriver in the lower slot (see
Figure 7) and turn to pry up meter cover (item 6).
4. The meter chamber (item 8, page 10) can now be
removed.
5. Rinse all meter components with ushing uid. DO
NOT submerge display assembly. Be careful not to
get any uid or dirt in the electronics module.
Permanent damage to the electronics will occur.
6. Reassemble meter.
CALIBRATION NOTE: Over time, the chamber inside the
meter will wear, requiring the meter to be re-calibrated with
water. When this should be done depends on the amount
and type of uid dispensed. In most crop protection uid
uses (less than 1000 gallons of a clean uid per year),
the meter will remain accurate for many years without
recalibration. On the other hand, dispensing an abrasive
uid may require more frequent recalibration.
The 825P / 850P meter is designed to be calibrated with
clean water for safe handling. See "Water Calibration"
section in Appendix - B.
Storage
Store in a cool, dry place. Drain out all uid that could
freeze in the meter.

Electrical Wiring Information
NOTE: When powering the 4-20mA loop, a minimum of
7 VDC is required at the 825P/850P meter for consistent
operation.
The manufacturer of the 4-20mA receiver will supply
voltage drop information as well as their minimum voltage
requirements in their literature.
NOTE: If the meter is to be used in environments with
high levels of EMC or RF sensitive equipment, connect
the braided shield of the cable to an earth ground.
The 825P / 850P meters are designed to conduct ESD
and EMC surges through the braided shield.
NOTE: The pulse width for volumetric output and air
detect is 10ms.
DO NOT connect the braided shield to the ground of the
Power Supply, or the 4-20mA loop power.
DO NOT install or operate this meter in an explosive
atmosphere!
825P / 850P Series Digital Meters are equipped with an
integral pulser for use with Fuel Management Systems
and batching equipment. These meters must also be
connected to an auxiliary external power supply to
operate the pulsing feature. 5-24 VDC external power is
required for the pulse outputs on pins 2 and 3 to operate.
Failure to attach external power can cause premature
battery failure. External power must be from 5 - 24
VDC.

APPENDIX - B Water Calibration
The 825P / 850P meter is designed to be re-calibrated
with water for safe handling. Over time, the chamber
inside the meter will wear. Recalibrating the meter with
clean water will insure that Table #1 (calibration table
page 4) is most accurate.
You will need a container of known volume, at least 5
gallons or larger. Do not exceed a 60 gallon container.

Manual de operación y seguridad

Para garantizar una operación segura y eciente, es
esencial leer y seguir todas las siguientes advertencias y
precauciones.
1. Los herbicidas de uso agrícola que circulan en el agua
pueden ser nocivos para la salud. El uso y la eliminación
de estos productos son actividades normadas por leyes y
procedimientos federales, estatales y locales.
2. Siga los procedimientos recomendados por el fabricante
del líquido cuando emplee el producto y limpie el medidor.
3. No sobrepase la presión del medidor interno de 8.2 bar /
120 PSI.
4. El uso o la instalación incorrectos de este producto
pueden provocar lesiones físicas graves o la muerte.
5. El medidor digital 825 y 850 no se debe utilizar con
líquidos inamables. NO emplee líquidos con un punto de
inamación inferior a 38 °C (100 °F), como la gasolina y el
alcohol.
6. NO retire la placa de circuito impreso.
Esto podría dañar la pantalla LCD y anular la garantía.
Instrucciones de seguridad
Los medidores Sotera 825P y 850P son de disco giratorio y
desplazamiento positivo y emplean acoplamiento magnético
para convertir el ujo de líquidos en información para la
pantalla digital. El medidor puede almacenar y presentar el
total actual o el total acumulado en cualquiera de las cinco
unidades programadas (onzas, pintas, cuartos de galón,
litros y galones) o en unidades especiales (por ejemplo, por
volumen en acres). Para calibrar el medidor sin administrar
líquido, seleccione un factor de calibración entre las 20
conguraciones almacenadas. La energía se suministra
mediante dos baterías CR2032 que se pueden reemplazar
en campo. Los modelos 825P y 850P cuentan con una salida
de pulso y salida de 4-20 mA para conectar a sistemas de
administración de líquido y controladores de dosicación para
controlar y monitorear el líquido dispensado.
No se debe utilizar con líquidos que tengan un punto de
inamación menor que 38 °C (100 °F; es decir: gasolina,
alcohol). Consulte NFPA 325M (Propiedades de los líquidos
inamables, gases y sólidos volátiles en caso de incendio)
para conocer los puntos de inamación de los líquidos
comunes. La acumulación y descarga de electricidad estática
pueden generar un arco y una explosión.

Descripción general
PELIGRO
Riesgo de
explosión

Los medidores digitales 825P y 850P toleran la mayoría
de los pesticidas, líquidos para uso en automóvil (excepto
gasolina) y ácidos moderados. También son compatibles con
los siguientes líquidos**:
Use una cinta de PTFE o un compuesto de inserción
en todas las juntas con rosca.
1. Determine la dirección del ujo de líquidos y apunte la
echa del cuerpo del medidor en dicha dirección.
2. Inserte la manguera o tubería en los puertos hasta que
quede ceñida. Tenga cuidado de no desalinear la rosca al
comenzar con la inserción.
Consejo para la instalación
Para evitar que la rosca se desalinee, gire la tubería o
manguera hacia atrás (hacia la izquierda), hasta sentir que se
sigue la rosca y luego apriete.
Cambio en la posición de lectura del medidor
Si es necesario cambiar la posición de lectura del medidor,
siga los pasos que se indican a continuación. (Consulte la
vista despiezada.)
1. Desinstale la tapa del medidor (elemento 1, página 10).
Utilice una llave de ltro de aceite tipo cuerda o una llave de
tipo mandíbula abierta de 5" si está demasiado apretada para
que salga manualmente.
2. Inserte un destornillador de paleta con cabeza fresada en
la ranura superior y ejerza un poco de presión en el módulo
electrónico (consulte la Figura 1).
Figura 1
RANURA DE PALANCA

RANURA DE PALANCA
INFERIOR
3. Gire suavemente el módulo electrónico hasta la ubicación
deseada.
Figura 2
JUNTA
TÓRICA
4. Presione el módulo electrónico hacia la cubierta del
medidor, hasta que adopte la orientación correcta.
5. Enrosque la tapa del medidor manualmente. Para
vericar el apriete, debería haber una separación de
aproximadamente 1.5 mm (1/16") entre la tapa y el borde del
puerto de salida (consulte la Figura 3).
SEPARACIÓN DE 1.5 mm

PRECAUCIÓN: El medidor cuenta el aire si se vierte aire.
Antes de que funcione por primera vez o cuando haya aire
en el sistema, cebe el medidor administrando líquido hasta
eliminar el aire atrapado. Ahora el medidor está listo para
funcionar.
1. Presione el botón ON (Encendido) para encender el
medidor. Aparecen el total actual, la unidad de medida y
el factor de calibración. El medidor también se enciende
de manera automática y comienza a registrar cuando se
inicia el paso de líquidos.

2. Mantenga el botón 4presionado durante un segundo
para jar el total actual en “0.00”.
3. Comience a administrar.
NOTA: La pantalla del medidor se borra automáticamente
tras 60 segundos de inactividad y se recupera en forma
automática al reactivarse el ujo. No se pierden datos debido
a los períodos de inactividad.
Funciones operacionales
• Enciende el medidor cuando está apagado.
• Presenta el total acumulado mientras
se mantenga presionado. Si el total
acumulado es mayor que 9999, los
números avanzarán por la pantalla.
• Cuando se presiona durante 3 segundos,
el total actual se restablece en cero.
También se restablece el modo de
funcionamiento normal en caso de estar en
modo CAL o FLSH.
• Al presionar durante 3 segundos, se
pueden realizar cambios en el factor de
calibración que aparece en la esquina
izquierda inferior. Presionar repetidamente
aumentará el número hasta 19 y luego
regresará a cero. Cuando aparezca el
número deseado, presione el botón 2
para jar el nuevo número y regresar al
funcionamiento normal.
• Cuando se presiona durante 3 segundos,
se muestra la velocidad de ujo. El líquido
administrado se suma al total acumulado y
al total actual. Presione el botón 4para
regresar al funcionamiento normal.

PRECAUCIÓN: Utilice el equipo de seguridad adecuado
cuando manipule líquidos peligrosos.
Calibración mediante el factor “CAL”
Mientras MENOS VISCOSO sea el líquido, MENOR será el
número CAL.
Mientras MÁS VISCOSO sea el líquido, MAYOR será el
número CAL.
• Se ja CAL 4 para líquidos no viscosos, como el agua.
• El mayor de los números, CAL 19, se ja para líquidos muy
viscosos, como las melazas frías.
• Cada número altera la precisión del medidor en alrededor
de 1 %.
Nota: Los factores CAL sugeridos son SOLO REFERENCIALES.
