Product Overview
The PEPT-1 and EPT-1XP are RecordALL’s high-resolution transmitters — two-wire electronic devices that put out an unscaled pulse equal to 21 pulses for every revolution of the meter’s measuring element. A magnet driven by the meter spins an optical disc that an infrared LED reads, so the count is all solid-state with no contacts to wear. On a 1/2 in. oscillating-piston meter that is about 1,170 pulses per gallon — many times the resolution a register drive can give, and exactly what a tight batch or fill needs to stop on target. The raw pulse connects to almost any controller or flow computer and is scaled to engineering units there. The two models share the same electronics and differ only in the housing: the PEPT-1 in corrosion-resistant plastic (NEMA 4X) and the EPT-1XP in cast bronze (NEMA 4, 7 & 9). Both field-retrofit to most Badger Meter Disc and OP meters and mount on the meter. Note that Badger Meter discontinued the cast-bronze EPT-1XP in 2021 (service parts available until stock is depleted); the plastic PEPT-1 is the current equivalent.
Two models, one electronics
PEPT-1 and EPT-1XP are the same two-wire high-resolution transmitter — 21 pulses per revolution, solid-state optical sensing, the same output. They differ only in the housing and its protection rating.
- Corrosion-resistant plastic enclosure
- NEMA 4X — watertight and corrosion-resistant
- The standard choice for general indoor and outdoor mounting
- Rugged cast-bronze housing
- Watertight, dust-tight NEMA 4, 7 & 9 — the rugged metal-enclosure rating
- Discontinued by Badger Meter in 2021 — service parts only until stock is depleted; the plastic PEPT-1 is the current equivalent
Key Features & Benefits
- 21 pulses per revolution — high-resolution unscaled pulse gives far finer resolution than a register-drive transmitter — about 1,170 pulses per gallon on a 1/2 in. OP meter
- Built for fine batching — the resolution to control a tight batch or fill, where a coarse pulse would overshoot
- Solid-state optical sensing — an infrared LED reads a slotted optical disc — all solid-state circuitry, no contacts to wear, for long life and high reliability
- Two-wire and simple — a two-wire electronic transmitter that connects to almost any controller and scales to engineering units there
- Two enclosures — the corrosion-resistant plastic PEPT-1 (NEMA 4X) is the current model; the rugged cast-bronze EPT-1XP (NEMA 4, 7 & 9) was discontinued by Badger Meter in 2021 (service parts only) — see Variants
- Field retrofit — fits most Badger Meter Disc and OP meters as a field upgrade to a high-resolution electronic output
Specifications
- Function
- Two-wire electronic high-resolution unscaled pulse transmitters — fine resolution for precise batching and totalizing off disc and oscillating-piston meters
- Models
- PEPT-1 (plastic enclosure — current) and EPT-1XP (cast-bronze enclosure — discontinued by Badger Meter in 2021, service parts only; the plastic PEPT-1 is the current equivalent) — see Variants
- Sensing
- Solid-state — an internal magnet driven by the meter is coupled to an optical disc; an infrared LED senses the slotted disc to generate the pulse
- Output
- Unscaled pulse — 21 pulses for every revolution of the meter’s measuring element (a 1/2 in. OP meter produces about 1,170 pulses per gallon); with the supplied interface module the pulse alternates between 1.4 and 10V DC, compatible with 12V CMOS controllers. Connects to almost any controller or flow computer that scales the unscaled pulse to engineering units
- Pulse resolution
- 21 pulses per revolution of the optical disc — high resolution for fine batching and tight totalizing control
- Meter compatibility
- Badger Meter Disc (M25/M35/M40/M70/M120/M170 RCDL) and OP (oscillating-piston) meter lines; field-retrofits to most Badger Meter flow meters
- Power
- Two-wire; the controller supplies 12–15V DC to operate the transmitter (the datasheet wiring uses a +12 to 24V DC supply through the supplied current regulator)
- Enclosure
- PEPT-1: corrosion-resistant plastic, NEMA 4X. EPT-1XP: cast bronze, watertight / dust-tight NEMA 4, 7 & 9. Rated −40 to 140°F (−40 to 60°C). See Variants
- Mounting
- Meter-mounted on a bayonet base; 18-gauge stranded-wire connections
Common Applications
- Batch and fill control where a coarse pulse would overshoot the target
- Inventory-control counting off disc and oscillating-piston meters
- Flow-rate indication and control through a scaling controller or flow computer
- Feeding any controller that accepts a 10V DC pulse and scales it to engineering units
To size & select the right PEPT-1 / EPT-1XP Transmitters:
Use the input form to tell us the meter and what the read-out has to do — a local total, a resettable rate / total counter, a scaled pulse or 4–20 mA into a PLC or SCADA, batch control, or a cellular cloud read — and we’ll match the register, transmitter or controller to it.
