Tenders invited for Supply of micror ratemeter
with calibration certificate
A 1959 Melville-Cornwall paper (8) described the use of their ratemeter in cardiac applications, for measuring the interval between each heartbeat but providing an output calibrated in beats per minute.
To deal with "the rather 'noisy' environment when recording fetal heart signals from an abdominal microphone", a ratemeter was developed that incorporated protection against random triggering, based on "an original bright idea that Alf had" (10).
The DPF80 Series (Dual Rate Totalizer) is a five-digit ratemeter
and a six-digit totalizer in a 1/8 DIN package.
Large, 40-bit deep counters complement a fast, 500 MHz counter/timer ratemeter
and digital/bar graph intelligent LCD.
Motor speed was measured with a magnetic pick-up mounted on the motor shaft and displayed on a Visi-tach digital ratemeter
Here the signal is the AC coupled via a blocking capacitor and passed on to pulse handling electronics such as the VG Quadrupoles SPC10 unit which combines a pre-amp, discriminator and ratemeter
in one unit.

and scaler Display: 4-digit (6 in scaler mode) LCD with 1.
This is only the first step," responded Heiko Kunst (DG Climate), emphasising the Commission's desire to limit costs and administrative burdens for operators by proposing four methods based on current tools: bunker fuel delivery notes, or BDN, hold inspections, ratemeters
and direct measurement of emissions.
Key features and benefits of totalizers, predetermining count/controls, ratemeters
, timers, digital panel meters, flow totalizers and controls, temperature indicators/controls, special function controls, specialty products, and transducers and accessories are included.
