ECHOTEL® 919
Universal ultrasonic
level switch
DESCRIPTION
With relay or all voltage
Echotel 919 ultrasonic level controls are compact integral
units which utilize pulsed wave technology to detect high or
low level alarm in a broad range of viscous to light liquids.
The 919 has protected electronics, and its high frequency
signal prevents the unit from picking up noise from surrounding equipment such as engines, pumps etc...
The Echotel 919 is available in two versions:
- all voltage unit (must be used in series with a load)
- unit with integrated relay (3A SPDT @ 24 V DC).

No calibration required.
330° rotatable housing.
Compact and easy to install design.
High or low level detection is field selectable via DIP
switch.
• High temperature / high pressure rating:
max. +150°C @ 103 bar (300°F @ 1500 psi).
• IP67, watertight, corrosion resistant Valox® enclosure
(IP54 with incl. cable gland).
• Sanitary finish: - 0,5 µm (Ra 20) surface finish
- seamless welded transducer gap
- horseshoe shaped transducer gap.

• LIQUIDS: Any liquids with a viscosity < 10.000 cP.
• VESSELS: Any mounting position, ideally for filters.
• PROCESS CONDITIONS: Unaffected by
- shifting dielectric, density, or PH
- presence of foam and visible vapors
- fast drain/fill rates
- vacuum conditions.

The Echotel 919 operates on a two crystal pulsed or “transmit-receive” principle which applies a high frequency electronic burst to the transmit crystal. The signal is then converted into ultrasonic sound energy and transmitted across
the sensing gap toward the receiver crystal. When there is
air in the gap, the high frequency sound energy will be
attenuated, thereby not allowing the energy to be received.
When there is liquid in the gap, the sound energy will propagate across the gap and the output will indicate such a
reception of the signal.

EXPEDITE SHIP PLAN (ESP)
Several Echotel 919 devices are available for quick shipment, within max 3 weeks after factory receipt of purchase order,
through the Expedite Ship Plan (ESP).
Models covered by ESP service are conveniently grey coded in the selection data charts.
To take advantage of ESP, simply match the grey coded model number codes (standard dimensions apply).
ESP service may not apply to orders of ten units or more. Contact your local representative for lead times on larger volume
orders, as well as other products and options.
