New load cell signal conditioner
The OM-19 load cell signal conditioner enables a weighing system to be controlled by a computer or programmable logic controller, eliminating the use of a digital display
Mainly used for strain gauge sensors such as load cells, torque, or pressure sensors, the OM-19 provides a voltage output of ±10 v DC or 0-10 v DC and current output of 4-20 mA, while supplying the needed excitation voltage to power up to four (350 ohm, 4 or 6 wire) strain gauge load cells (350 ohm)
Available in board only, DIN rail, or industrial enclosure versions, it can be used in a range of applications and environments. All three versions are equipped with a shunt calibration feature. A solid-state relay output option with two set points (OM-19-2S) is also available

New ultrasonic flowmeter
The new Innova-Sonic in-line ultrasonic flowmeter is an alternative choice for typical liquid mag-meter applications
It offers ±0.5% of reading accuracy and has the ability to measure down to zero flow and virtually any clean liquid regardless of conductivity.
The firm’s PicoFly technology allows ultrasonic transit time-of-flight to be measured in picoseconds (one trillionth of a second) rather than nanoseconds (one billionth of a second). The result is excellent resolution that enables extreme low flow detection, the company notes
The unit features high precision, high reliability, high capability, low power consumption, digital signal processing with advanced noise filtering capability, and good applicability. Repeatability is ±0.07% of reading, operating temperature range is –40° F. to +176° F., and bidirectional flow range is 0-23 fps (0-7 mps) liquids.
